Does it make sense to independently make a transparent concrete. Transparent concrete

Svetopropy building materials represent the result of innovative and expensive construction technologies. As a light-conducting filler, fiberglass with percentage content is not more than 5%, which makes it possible to maintain the basic properties of concrete: tensile strength and compression, waterproofability, frost resistance. At the same time, the design potential of the material is huge: being not completely transparent, the blocks skip the lights and change the pattern when the lighting changes.

In the absence of a large-scale filler, fiberglass acts an analogue of fibra and withstands internal and external loads and deformations. The only disadvantage is high rates (from 90,000 rubles per 1 m2), the technology of transparent transparent concrete is still mastered by Russian manufacturers and is considered expensive.

Composition and properties of material

The raw material serves cement, sand with a dimension module 2-3, fibroid fiber with a filament diameter from 0.5 to 2.5 mm, modifying additives to improve the formility of sedimary solutions. The large-scale filler is absent, the percentage ratio of the light-resistant lies within 4-5%. Optical characteristics of fiberglass and environmental friendliness of raw materials from finished products are certified, it is completely safe for humans, even with the introduction of plastic resins. In fact, the transparent type of concrete has the same properties as the usual:

strength: on compression within 20-35 MPa, for stretching with bending - at least 2;
density - 2300 kg / cm3;
thermal conductivity - 2.1 W / (m ∙ k);
frost resistance up to 75 cycles;
brand of water permeability: W4-W8;
water absorption: not more than 6%;
soundproofing - 46 dB.

The material is not lit, not afraid of UV rays, there is a risk of alkaline-silicate fiberglass reactions with cement under the influence of atmospheric precipitation, but due to the thin cross section of the threads it is minimal. During the day, concrete misses the natural light, at night - artificial. In the theory, the thickness of the slabs is not limited, in practice it does not exceed 20 cm due to the current possibilities of laying fiberglass. The production of transparent concrete is constantly improving, but is still exclusive and expensive technology.

Scope of application

The manufacturer produces blocks and plates of white, black and gray, with a special processing of surfaces (polished or matte). This concrete is used in decorative purposes, due to the high cost, the full-fledged construction of the walls is possible only in the construction of unique objects. It is optimal for interior decoration: partitions, cladding with laying lamps under tile, stairs, inserts. The original view has furniture and interior items from a transparent composite: benches, countertops, lamps, sinks.

Blocks are connected by a mortar on a cement or lime-based or compositions of epoxy resins and quartz crumbs. Such masonry corresponds to construction and fire provisions and is suitable for the construction of bearing walls. In addition to the fastener, the anchor bolts or frameworks are bought, the panels may have an outdoor execution. The only limitation of the application is the high price of transparent concrete, for private construction it is advisable to try to make it yourself.

Production technology

The process is a layer laying of fiberglass filaments and a fine-grained concrete mix. After a durability set, the transparent concrete is processed: grinding and polishing. This is necessary to obtain optimal lighting characteristics and enhance the decorative effect. Optical properties depend not on the thickness of the plates, but from the uniformity of the distribution of the threads and their percentage ratio. Blocks with a finely structured structure look air and transmit objects of the object, with an increase in the location density of the fibers, the transmitting effect is stronger.

Much depends on the mobility of the mixtures: the offset leads to a decrease in bandwidth, but creates a unique pattern. It is important to understand: the technology of production of transparent concrete with light-resistant abilities does not allow it directly on the construction site. The process of creating a separate panel labor-intensive and takes a lot of time (as well as delivery from abroad), it should be considered when planning the timing of work. If necessary (to obtain the plates of the necessary thickness), the material is subjected to the cut perpendicular to the stacked threads.

Independent manufacture

It is quite realistic to create it with your own hands, the main thing is to achieve the maximum homogeneity of the solution and immobility of fiberglass. Recommended proportions are:

1 part of cement;
2.3-3 sand without clay impurities and dust;
0.5 pieces of clean water.

The volume of the lighting filler does not exceed 5% of the total mass of the solution, the thread diameter is 0.5-2.5 mm, the length corresponds to the thickness of the concrete product. To reduce the mobility of the mixture, it is recommended to enter modifying additives. It is not suitable for their own hands, it is best to prepare a solution in forced mixers and small portions. Water is introduced after the compounding of sand with cement (the finished mixtures are welcome), after the introduction of all components, the concrete is mixed at least 5-8 minutes.

A sliding type of formwork is used. Transparent concrete is styled in stages: 0.5-1 cm of solution and slightly cannon fibers or bundles. Important: Each subsequent layer is laid exclusively after grabbing the previous one. After filling, the formwork is left fixed by 48-72 h and only then removed. The minimum set of strength is 5-7 days, to which the product is maintained at 20 ° C and humidity 95%. After the frozen, all the edges of the fibers are covered with cement, to achieve transmitting properties, the surface needs to be finished - grinding the side faces with diamond disks.

Cost

In addition to the brand "Transparent Concrete", this product is known to the consumer as a literone or a hat (according to the European Marks of the same name). Rates are indicated taking into account the recalculation of the euro, when planning the purchase, you should remember the additional costs of delivery. It is possible to produce panels with individual parameters, up to the location of fiberglass in the form of logos and paintings. In this case, the cost will be negotiable, as well as when creating to order colored blocks with LED lighting systems, curved forms or interior items.

Transparent concrete - production technology with their own hands

For more than 50 years, concrete is the most popular building material. Due to high strength, density and resistance to temperature differences, concrete bases serve longer. But, this material has pretty scanty aesthetic indicators, which significantly narrows the scope of its use during construction. To solve this problem, a transparent concrete was developed (or as it is also called the light or "literon"). This is an innovative material that only begins to conquer the market. Consider more, which is part of this material, what properties it has and where it is used.

What is the transparent concrete

This modification was developed by architect from Hungary by Arone Hoshonzi, which experimented with construction materials. With his light hand 15 years ago, a lightweight concrete appeared on the light, which consists of:

cement;
fine-grained sand;
fibroid fibers (thread diameter 0.5-2.5 mm), which perform the role of light filler;
specialized additives that improve the formability of a low-propelled solution.

Localized fillers in the manufacture of translucent concrete are not used.

Fiber optic glass threads are necessarily certified. The documents indicate that the material is environmentally friendly.

Immediately it is worth saying that the cost of high-quality transparent concrete is very high, if you have the opportunity, it is better to order material from Europe. Nevertheless, domestic producers have already begun to master the technology of production of this unique composition. True, the price of this has decreased not much.

Cost of transparent concrete

Today, two Litracon and Lucem are engaged in the Russian market for the sale of this unique material. However, it is worth considering that these companies are not manufacturers. These are the mediators of official European companies that are just manufactured by a glowing concrete. Accordingly, the cost is not taken into account.

However, you can order decorative plates of any size, shape or color. You can even buy the canvas in which fiber fiber fibers will be laid out in the form of a logo or product, as well as blocks equipped with LED backlight. Of course, the cost in this case will be several times higher.

If we talk about the price of "typical" panels from a transparent material, then:

The Litracon Classic Panel of 1200 x 400 mm in size and 25 mm thick will cost at least 90,000 rubles. If the thickness is increased to 200 mm, then it will cost 320,000 rubles.
A little cheaper will cost the Litracube LAMP unit with a size of 221 x 175 x 175 mm and a thickness of 25 mm. For it you can pay from 54,000 rubles.
Light concrete plate from Lucem (1250 x 650 mm) with a thickness of 15-50 mm will cost at least 90,000 rubles.
Luminous LUCEM tabletop with a size of 1200 x 600 mm will cost 89,500 rubles.

All prices include shipping cost.

Many believe that due to their transparent structure, such a concrete has very low strength indicators and other characteristics. Consider them in more detail.

Properties of transparent concrete

Despite its transparency, this material has the same properties as ordinary concrete. Moreover, according to some indicators, he even surpasses his "gray fellow". This is explained by the fact that its composition contains fiberglass, which is an excellent reinforcing material.

The luminous material has the following characteristics:

durability: compression in a range of 20-35 MPa, on bend 30 ptb, and no less than 2 stretching;
density - 2300 kg / cm3;
thermal conductivity - 2.1 W / (m ∙ k);
frost resistance to F75;
waterproof - W4-W8;
sound insulation properties - 46 dB;
water absorption within 6%.

At the same time, the material freely transmitting the light beam does not have any influence of UV radiation. However, there is a risk of insignificant alkaline-silicate reactions in the case of heavy precipitation. Therefore, it is better to choose products with a thinner cross section of threads, then damage will be minimal.

The thickness of the plates of transparent concrete usually does not exceed 20 cm. However, this indicator does not affect the light-brain ability of the material. Even if the wall thickness is 2 m, the light will still go through it through it.

In the afternoon, the slabs are missing natural light, and at night - artificial, thanks to which you can achieve very unusual design decisions both in the interior of the apartment and when building a country house.

Scope of application of transparent concrete

Since blocks are produced any size and color, polished or matte, their scope is not limited. Products of this type can be used in construction. They are optimal for interior decoration, as well as under construction:

partitions;
stairs;
inserts and much more.

The luminous panel is allowed to be used on a par with products from standard concrete. However, the cost of a transparent building material is so high that it is used only when the buildings of a special architectural value are erected.

If we talk about ordinary citizens, then they often apply this unusual composite for the manufacture:

benches;
countertops;
shells;
decorative fountains;
distorted niches in the walls.

If you spend on small panels, you can make a cube from them and put the lamp inside it. So you will get a very unusual lamp.

Also, from a transparent concrete you can make a bar counter, which will be separated by the kitchen and bedroom in the studio apartment.

Of course, buying 90,000 rubles for the usual night light. In this case, the transparent composite can be tried to make it on its own.

How to cook transparent concrete

First of all, it is worth saying that specialized equipment is required to produce such a composite. Since the composition components are placed in layers, after each subsequent layer requires processing. Nevertheless, there are handicraft methods that allow you to prepare a material that resembles a transparent concrete, with your own hands.

This will require:

1 share of PC;
2.5-3 Sand shares (it should not contain loam and dust);
lightwater filler - (no more than 5% of the total mass of the kneading);
modifying additives.
0.5 parts of running water.

The solution is mixed in a forced mixer (it is better to prepare concrete with small portions). First you need to shift sand and cement. After that, water is added to the mixture, and the solution is mixed at least 6 minutes. At the following stages, a sliding formwork is prepared, and the following operations are manufactured:

The formwork is laid out a layer of concrete of about 0.5-1 cm high.
A layer of fibers is stacked on it (they need to be pressed a little).
After that, it is necessary to wait until the layer "grab".
The procedure is repeated until full filling of the formwork design.

After that, it is necessary to wait for about 72 hours and remove the formwork. For a week, the workpiece must be stored at a temperature of +20 degrees and air humidity at least 95%. After 7 days, the concrete will take maximum strength, then it will be possible to grind surfaces. For finishing processing, it is best to use diamond discs.

Finished blocks are mounted using standard masonry mixtures. For gluing products, it is possible to use an epoxy resin with a quartz filler.

In custody

Transparent concrete is a very expensive pleasure, so no one uses it to build houses. However, if you apply it to decorative purposes, you can achieve a stunning effect.

Translucent concrete: As created and where it is applied

Modern building material - transparent concrete, opens up new opportunities for construction and decoration of buildings

Anyone man on the planet knows how concrete looks like: gray rods are familiar with everyone and everyone. The popularity of the concrete solution is very high, because, despite its external unattractiveness, this building material is very durable and rather economical.

But science does not stand still, and today we will tell about the new material that has received the international name Litracon (literon) or translucent concrete. We will analyze, from which the new type of concrete is, for which it is used, and it is possible to make glassboxes with their own hands.

Litracon technology allows you to create various drawings in blocks, including the image of trading brands

When, who and why?

The pouring of a concrete solution of any formwork shape creates a very solid construction that has a very long service life. The initial plasticity of the material and the maximum strength after frozen, make it very popular in the construction market of the whole world.

But among the many advantages of concrete, it has several drawbacks. The main of them is the outer unattractiveness of the surface. Due to serness, concrete surfaces require a mandatory decorative finish.

Who and when did the transparent concrete come up with?

In 2001, Architect from Hungary, Aron Loscone looked at the problem of concrete surfaces from the inside. He decided that the external unattractiveness of concrete could be corrected not by externally decorative materials, but by changing its internal structure. As a result of the experimentation cycle, a new, technological building material appeared on the light - transparent concrete.

Hungarian Architect Arone Loskone, along with its invention - transparent concrete

Concrete transparent, having a very attractive appearance, did not immediately gain popularity. As a material for the construction of parts of buildings and structures, it was first used in Europe, in Germany in 2005.

In Russia, transparent blocks from concrete got in 2012. And in our country its use is quite limited. There is no domestic analogues to this material, and it is quite expensive to import it from abroad. The price of a block weighing 10 kg is about 600 euros excluding delivery and customs duty.

For what?

The transparency of the licontrack is quite relative. By the degree of transmitting light it is difficult to compare with glass. Nevertheless, the use of blocks for the construction of walls or partitions can significantly reduce the amount of electricity consumed, passing the inside of the room natural lighting.

At the same time, you will not be located inside a glass cube, translucent blocks retain a certain intimacy: Through the wall from the lump button, you can only distinguish the silhouette or guess the color - provided that there will be independent lighting.

On a note! The thickness of the block or the transparent concrete panel does not affect its light-resistant ability. The underlying condition for the manifestation of this effect is the presence of a light source.

The difference in the lightweight capabilities of concrete liter and ordinary glass

Transparent concrete

In fact, transparent concrete is blocks of fiberglass, poured by concrete solution. In addition to external appeal, the author of the invention was looking for a way to ensure the access of light into a concrete building, while not disturbing the main strength characteristics.

Definition and composition

Ordinary concrete blocks are a mixture of cement, sand and rubble. The transparency of the material is achieved by adding to the composition of the optical fiber.

In this case, there is no need to use aggregate of a large fraction and additional internal armature. Therefore, transparent concrete blocks do not differ in strength from ordinary concrete, while obtaining additional aesthetic appeal.

The mass fraction of the optical fiber in the blocks of transparent concrete is no more than 5%. The diameter of the fiberglass used may be different, but is in the range from 2 microns to 2 mm. The main volume is gained by cement and fine-grained purified sand.

On a note! Compared to a conventional concrete composition, this material has much less weight, but it becomes much stronger.

Fiberglass creates a reflective matrix that allows concrete to skip light

Performance features

So, we found out that fiber optic in concrete gives blocks the ability to skip light. What is the situation with other concrete characteristics that builders attract so?

Fiberglass is simultaneously enhancing the element of reinforcement, due to which the transparent blocks acquire higher indicators of the following properties:

resistance from the destructive impact of humidity;
strength of material for bending and compression;
resistance to the effects of temperature differences.

At the same time, indicators are preserved in terms of environmental friendly, fire safety, sound and thermal insulation. Also, transparent concrete is not subject to ultraviolet rays.

It does not fade and does not change the picture. The modern building market offers to buy blocks from translucent concrete black, gray and white.

Application area

At the moment, literone has gained enormous popularity with the designs of interiors and designers of buildings, both in the field of low-rise construction and in the field of industrial development. Transparent concrete blocks perfectly fit into the structure of modern and high-tech buildings.

We produce blocks and panels of translucent concrete, which are using tremendous success:

as the main material of the bearing walls;

The walls of the office building are posted from blocks of transparent concrete

for the inner and external facing of the building surfaces, including the floor;

Interior decoration with plates of transparent concrete

for the formation of zonal fencing and device of interroom partitions;

Translucent Front Wall Administrative Rack Reception Zone

Maf (small architectural forms) is made of transparent concrete: benches, fountains, plafoons for street lamps.

Elements of a transparent concrete

Like any stone with an interesting structure, transparent concrete found its use as a staircase staples, worktops and in the manufacture of sanitary furniture. In the photo below, examples of the successful use of the material of the Litrakon brand:

Process of production

The technology of production of transparent concrete - the process is not complicated. The high cost of the material is not due to labor costs for production, but the cost of fiber optic that is part of the blocks and panels. The layer of concrete is poured into the formwork without a large-scale component, then the fiberglass is pressed into the solution and the layer dries.

Next, the process is repeated. The fill of the next layer always occurs after the previous one grabbed. Thus, a transparent concrete is obtained: its production technology is not a high-tech or labor process. Perform the work on the manufacture of glassbobetone is quite independently.

We make litractons on their own

Due to the high cost of corporate material, many try to make a transparent concrete with their own hands. Technologically, this process is very simple, but there are nuances here. The cunning consists in compliance with the exact proportions of all components, as well as as fillers.

In addition, it is very important to observe the styling of filament filaments.

To make a block or panel glass with your own hands, you need to prepare the following materials:

Concrete solution is prepared in the traditional proportion one to three. Water is added as needed, based on the mass fraction of cement, but the amount of water in the solution should not exceed 50% of the total volume.

Important! It should be carefully produced, for which it is necessary to use special equipment (concrete mixer), the state of which should be absolutely clean.

Instructions for pouring blocks Next:

Floating, moving up the formwork is going to the box;
The first thin layer of the concrete solution is poured inside the formwork;
Fiberglass is fitted and dried into the solution;
Pouring leaves at rest until the concrete is set.

Next, the process repeats the required number of times to a set of full height. After the last layer of the fill grabbed, the formwork is removed. This usually occurs after 48 - 72 hours from the moment of filling the last layer.

Important! After removing the formwork, the block is given to be sealing in room temperature and medium humidity within 3-5 days.

The finished block is polished and polished to the mirror gloss on the side of the working surface, which is perpendicular to the direction of laying fiber fiber. You can read more about the process of independent manufacture of translucent concrete blocks by looking at the video in this article.

Installation of panels and blocks

Translucent concrete blocks or panels can be used to finish the facades and for the formation of internal surfaces. The layout of the blocks is made on a binding cement-lime solution, or using adhesive compositions based on epoxy resins and quartz flour. The strength of the walls is not inferior to concrete masonry, and meets all the requirements for the carrying elements of the building design.

The panels from transparent concrete are attached to a frame or anchor mounts. Their device is similar to the technology of the device of ventilated facades. Also panels can be laid as an outdoor coating. The strength of the material does not depend on the thickness of the tile.

The photo clearly shows that the panels of the blocks of transparent concrete are mounted on the metal frame wall

Conclusion

Modern concrete transparent has very interesting external characteristics, while maintaining all the valuable performance of ordinary concrete. This combination makes it very attractive in the construction of concrete buildings with unusual structural elements. If the price of the material seems very high, you can make a light concrete blocks with your own hands.

What is the transparent concrete?

The cornerstone of modern architecture can safely call concrete, because without it is not a single serious project. However, the aesthetic component of structures from it most often lost and could be partially compensated due to the scale, intricateness and complexity of forms. So it was as long as in 2001, a clear concrete was not invented by the young Hungarian architect, in the fine-grained structure of which glass fiber-optic threads are included. Now the idea of \u200b\u200bit can significantly change - Lucem (one of the innovation names) acquires signs of air decorativeness.

Characteristics and properties

The lighting design is a solid and durable substance, permeated with a variety of thin glass fibers. Due to the technological complexity of execution, the price of a transparent concrete is quite high - about € 4,000 per m2 with a thickness of 200 mm, so it is produced exclusively to order in the form of rectangular plates, the dimensions of which are stipulated with the customer.

Despite some external extravagance and apparent weightlessness, Litracon retains the structural characteristics of ordinary concrete: strength, water resistance, noise and thermal insulation.

Moreover, due to the reinforcing action of fiberglass, individual indicators are significantly improved:

frost resistance - F 50;
disagrement - up to 6%;
compressive strength - M250 and bending - PTB30.

At the same time, the light-conducting properties of Lyceum do not depend on its thickness. The raw materials used in the production of a lightweight concrete is certified and before entering the plant undergoes an environmental impact assessment, it allows you to produce guaranteed clean and safe products.

The technological complexity of obtaining a transparent concrete does not allow to receive it, like the usual, pouring into the formwork right at the installation site. It is issued on specialized industrial enterprises with appropriate equipment.

Concrete production technology with glass fiber-optic threads involves layer-by-layer imposition of fine-grained solution and fiberglass. After grapping and set the required strength, the surface of each block is additionally processed to give the specified mass parameters and achieve the necessary lighting characteristics.

Application

The first product from the lightweight concrete was the fancy lamp in the form of a cube, made for demonstration purposes. Weighed this subject of home interior more than 10 kg. Since he called an unprecedented excitement, it can also be purchased at the exhibitions of innovation for 570 €.

Basically, transparent or lightweight concrete is used in the newest architectural compositions in decorative purposes, to implement bold design solutions in the city design, creating original interior elements. The fantasy of designers and artists is still limiting the high cost if a way to get around this obstacle will be found, the world expects many amazing innovations.

How to make it yourself

The complexity of independent production is to include in the structure of 4% fiber from the total mass, while the threads must be oriented in a certain way.

In order to get the Litrocon with their own hands, you should stock all the necessary materials:

dry fine-grained mixture for concrete;
pure water;
fiberglass (diameter 0.25 ÷ 3 mm) of the same length corresponding to the thickness of the future plate.

First of all, you need to make a design that resembles a box, but actually being a sliding formwork. As concrete sets down, it should smoothly shift up. The box of rectangular shape and the specified sizes are installed on a flat horizontal surface. On the bottom you need to pour a small amount of finished concrete by fixing its quantity, and distribute a thin layer.

On the resulting pillow across the form neatly, evenly put fibers and drown them slightly. After setting the composition, it was dosed into pour the next portion of the liquid concrete solution and again put on its surface fiberglass. The procedure is repeated to the final filling of the form.

After the last layer is freezed, the formwork is removed and grinding and polishing the side surfaces of the plate, in relation to which the fibers are perpendicular. If everything is performed correctly, then the prototype product is ready. Work will require time, perseverance and perpetuity, but the result is worth it. Taking into account the experience gained, subsequent products may be higher quality.

Buy in Moscow

Abroad, transparent concrete is very expensive, the costs associated with transportation and customs were added to this. However, the domestic engineering thought is not standing on the spot and now in our country they learned how to produce such a design material, the cost of which, as they say, is significantly lower than abroad. In Moscow, buy owls as import and domestic production. At the same time, the quality of the optical characteristics of the concrete of doubts does not cause, but prices, alas, are opaque. You can only find out if the order for products is decorated and the manager will be seriously the seriousness of the client's intentions.

Than concrete, but even its modern technologies did not bypassed. Not so long ago, literkon appeared on the market - a transparent variety of concrete. We will tell about its composition, features and spheres of application in our article.

The history of the use of concrete in construction has not one thousand years. The mixture that appeared about 60 centuries ago is still the basis of both multi-storey projects and private sector buildings. The only drawback of concrete is its visual unattractiveness - with interest overlapped with the strength of the composition and a wide range of applications.

As a rule, the serness of concrete walls is masked in various ways: all sorts of mixtures for decorative plastering, hinged facades, plastic and metal siding or painting with various tinted impregnations come to the rescue.

Hungarian architect Arone Loskone decided to look at the problem wider, offering the method of transformation of concrete not outside, but from the inside. The result of long experiments with the composition has become unparalleled new product - a transparent blue-conductive concrete. In 2001, Aron patented an innovative composition, which received the international name Litracon (literon).

Transparent concrete was developed for "clarifying" office space, but for the first time in direct appointment was used only in 2005 during the construction of a mansion in Germany.

What made transparent concrete

The Svetranda Svetrandopusca is conditioner: In fact, it is possible to see only the contours or the color of the silhouettes behind it. In this case, the room should be covered from the inside. In bad weather or evening, transparent concrete is not different from the classic option, its amazing properties exhibits artificial lighting or sunlight.

The composition of the lifrocember includes fine-grained concrete and fibroid fiber (fiberglass), which creates a reflective matrix. The diameter of glass fibers varies from 2 microns to 2 millimeters, and the percentage share is about 5% of the total mass of concrete.

Fiber optic equipment does not have a tangible effect on the strength, sound and noise insulating characteristics of the material, therefore, in all properties, the liter is equated to concrete.

Scope of application. Specifications of lightweight concrete

Svetopropuscent concrete has become a real discovery for designers and designers. Due to its originality, it can be used for buildings and facilities in the style of Hi-Tech and Modern:

Walling.
Interior partitions.
Facing the surface of the walls and columns.
Architectural forms - fountains, lamps, benches.
Household use - countertops, washbasins.
Erecting bearing walls.

The only minus of the lifroception is its transcendent value, reaching several thousand euros per square meter. The price category due to the use of very non-cheap fiber, makes the translucent concrete inaccessible for mass building. However, for decorating and zoning various rooms, liter is used more and more.

The German concern LUCEM currently produces blocks and panels from light-preparing material under the timing stamp of the same name:

The facial surface of the blocks and panels is polished to the mirror glitter.

Installation and operational features

The liter is immune to the temperature differences and ultraviolet rays, therefore, it can be used for both internal and facade works.

The lighting concrete blocks are laid out with the help of mortars on a limestone or cement basis or glued with a special composition based on epoxy resins and quartz flour. The laying of lontaset complies with all safety standards, including firefighters, and can be used for bearing walls.

Transparent concrete panels are designed for interior decoration. They can be mounted on the walls using frame structures or anchor bolts, as well as applied as floor coatings.

It should be noted that the thickness of the lolt oil is not reflected in its lighting ability, the sole condition is the presence of a light source.

The high cost of the novelty made it inaccessible for a wide range of buyers. In Russia, the translucent concrete is not yet available. Amateurs exclusive can pamper themselves with a custom "lamp" from abroad. True, this pleasure will fly into a penny: a ten-flame cube costs about 600 euros excluding shipping.

Olga Danyushkin, RMNT.ru

For more than half a century, concrete remains one of the most sought-after building materials. The combination of high strength, resistance to external influences and durability allows you to create a building based on this material, which exceeds 50 years.

The main problem of concrete has always been its low aesthetics and unsuitability for creating interesting design and architectural solutions. That is why transparent concrete after its appearance became a real find for many designers. The ability of such a durable and dense material to skip the light allowed to create a new generation interior.

Features and basic properties of the composite

His advent of a unique concrete is obliged to Hungarian Arone Hoshonzi. In search of ways to add light premises, retaining the structural reliability of concrete, the architect came to the conclusion that the modification of the material should be carried out from the inside, changing its structure.

As a result of numerous experiments, a transparent concrete appeared for about 15 years ago, made on the basis of fine-grained composite and fiberglass as a basic light-conducting aggregate. The created material was called "Litrakon".

The production technology of transparent concrete has undergone changes, but still very specific. Pouring massive structures with such a composite is impossible due to the complexity of the distribution of fibers. As a result, the optimal form of release has become blocks.

In fact, in the manufacture of material, the bundles of glass fibers are laid between the layers of fine-grained concrete. After hardening in the body of the material there is a large amount of conductive elements that create a unique light pattern in the body of concrete.

Despite the specific appearance, the transparent concrete is produced using the technology of a classic fine-grained composite, therefore possesses all the basic properties of this material. The main characteristics of the material include:

compressive strength from 20 to 35 MPa;
tensile strength for bending of at least 2 MPa;
water resistance at the W4 - W8 level;
frost resistance of at least 75 cycles;
water absorption does not exceed 6%.

The absence of large aggregate in the body of the composite increases the possibility of deformations and shear, so fiberglass for transparent concrete additionally performs the function of internal reinforcement, being a certain fiber analogue.

In production conditions, phased casting technology or layered vibropressing can be used for the manufacture of material. Both variants provide reliable fiber mount while maintaining the high performance of the composite as a whole.

Despite the seeming difficulty of execution, transparent concrete can be made with their own hands, attaching a little effort and effort.

Application of the composite

Unique material is most often used in decorative purposes. High strength allows you to erect internal partitions in rooms, providing access for more light. This embodiment of the inner walls is especially in demand in office space, with cafes and restaurants, as well as entertainment complexes.

A tile for finishing walls, floor or ceiling is often cut from the transparent composite. The use of material as the main in the construction of buildings in principle is possible, but it is not economically appropriate. The cost of transparent concrete is extremely high, and the performance of any technological line will not be able to ensure the needs of full-fledged construction.

In addition, the glass fiber under the influence of external moisture and temperature differences can enter into alkaline-silicate reactions with cement stone minerals, which leads to the destruction of the material.

The combination of all factors led to the fact that the unique composite remains a very exotic finishing material used to create decorative partitions, as well as decor elements.

Independent manufacture

To create a transparent concrete with your own hands, you will not need special equipment or specific skills. It is possible to make it at home. In fact, a good formwork will be required to prepare such material and attentive adherence to technology.

Materials and equipment

For the manufacture of a solution, it is best to use a compulsory mixer capable of ensuring a high degree of uniformity of a low-lifting mixture. When using a gravitational mixer, it is necessary to reduce the volume of the unit kneading and increase the mixing time at least 2 times.

From raw materials will be needed:

cement or mixed binder;
sand for construction work 1 class with a module of 2 - 3;
fiberglass with a diameter of 0.5 - 2.5 mm and a length of the thickness of the product;
modifiers that improve the formability of low-fat mixtures.

The use of movable mixtures implies the rapid setting of each layer of fine-grained concrete, to which the beams of glass fibers are stacked. It is easier to perform layers of sedentary mixtures capable of keeping the form after the seal.

Special modifiers contribute to the density and uniform structure of the base composite for transparent concrete. Sand should be used mid-size with a minimum amount of impurities, dust and or etched particles.

Composition and preparation of fine-grained concrete

To perform the basic composite, it is best to mix cement and sand in a ratio of 1: 2.5-3 by weight. The amount of water should not exceed half the mass of cement. In general, the composition of fine-grained concrete per 1 m3 can be represented as follows:

cement \u003d 450 - 500 kg;
sand \u003d 1300 - 1500 kg;
water \u003d 200 - 250 kg.

When using modifiers, their dosage is assigned in accordance with the manufacturer's recommendations. After loading into the mixer, the sand and cement is mixed within a minute before receiving a homogeneous mixture, the indolation water is introduced, and a mixing is ensured at least 5 to 8 minutes. After receiving a homogeneous mixture, the production of transparent concrete begins.

For the manufacture of the composite, the formwork is prepared with the base in the form of a rectangle. A kind of block is filled with a mixture of several stages. First, the lower layer of fine-grained concrete is compacted with a thickness of no more than 0.5 - 1 cm thick and compacted. Then the beams of fiberglass are then stacked so as to close almost the entire surface of the concrete.

The next layer of fine-grained concrete is stacked and compacted. From above, a new grid made of glass fibers laid across. Then the procedure is repeated before filling the formwork.

By changing the direction of fiberglass beams, the light will be able to pass through all the side faces of the manufactured unit. Of course, the frequency of conductive elements will be less common than that of the material of the factory manufacture, but the decorative properties of the composite will save.

The use of movable mixtures leads to uneven distribution and displacement of fiber beams. Such an effect slightly worsens the conductivity for light, but creates an interesting pattern in the body of the material. When using a movable mixture, the laying of the new layer is conducted after the loss of mobility of the previous one.

Finish treatment

The product is produced in 48 - 72 hours after the manufacture. Next, the block is kept at a temperature of 20 ° C and a humidity of 95% for 3 to 5 days. During this period, the concrete will acquire up to 80% of its strength and will be able to withstand the final processing.

After the platform, all fiberglass bundles are tightened with cement milk, so they do not conduct light. To give the material of the lighting properties, all side surfaces of the block must be pulled by diamond discs of various grain.

If desired, the product can be cut into the tiles of a given thickness. Cuts must be carried out perpendicular to layers of laying.

Concrete is one of the most durable building materials with extremely high technical and operational characteristics. The indisputable advantage of the material under consideration is a long service life. Despite the fact that the concrete composition has a number of advantages, without flaws it did not cost.
The main disadvantage of the cement composition is the unattractiveness of the appearance, it requires a decorative decoration. However, construction technologies develop with seven-world steps. As a result, technologists have developed a fundamentally new type of concrete - translucent.
We are talking about building material that allows you to create realistic silhouettes of animals and people, which, in fact, is a magnificent designer solution when building objects, buildings. Transparent concrete is easy to make a personnel personally, which helps reduce costs for expensive building materials.

Determination of transparent concrete
Transparent concrete is a unique building material invented by Mr. Horst, one of the leading Hungarian architects. He was looking for opportunities to ensure its designs with additional lighting, while technically the characteristics of the cement composition are in no way deteriorate. As a result, the architect decided to change the internal components of the building material.
After 15 years of incessant searches and experiments, he managed to develop and introduce a fundamentally new decorative and finishing material in the construction industry - transparent concrete. He got the name of liter. The material is introduced composite fine-grained compounds based on fiberglass.
The main disadvantage of transparent concrete - production is impossible on a large scale and volumes, so they are mainly produced in the form of building blocks.

Despite the obvious advantages of transparent concrete, you should not leave without attention and the key drawback is the high price applied by materials. Total price tag approaches several thousand dollars.

Specifications and features of transparent concrete
Transparent concrete is distinguished not only by a unique appearance, but also in the following characteristics:

thermal insulation;
water resistance;
high strength characteristics;
the possibility of personnel production;
noise isolation.

Since the cement includes fiberglass, a pronounced reinforcing effect is provided in the material. This contributes to the improvement of the real characteristics of the composition:

high flexural strength and compression;
frost resistance;
the level of moisture absorption rises to 6%.

One of the main advantages of the modern luxury is environmental cleanliness and safety. The characteristics of the material are certified. The minus of the material is the inability to get a lighting composition at the construction site, where the finished formwork is installed.

The light is passed due to the special fiber, which is part of the building material. Due to it, transmitting lights better on the length of up to 2 m. Fiber optic resistant to temperature fluctuations, thermal exposure, ultraviolet radiation.
During the daytime, such a transparent concrete passes natural light inside the residential space. In such a way, it is possible to ensure indoor lighting the household plot, the garden zone. The sale of gray, white and black colors is on sale. The lighting elements are fixed by construction solutions, anchors, or other fixing compositions. To date, blocks are available in various colors.

Scope of transparent concrete
Litracomon is used to form unique design elements:

inland partitions;
stairs;
countertops;
facades of structures.

It's time to dwell on the technology of production of transparent concrete with your own hands.

Technology production of transparent concrete with their own hands
The production of transparent concrete can be organized and with their own hands, if you carefully approach the technological process. The main problem is the technological complexity of the preparation of a lifone, and to be more accurate, then the need for a clear observance of the necessary ingredients.
To obtain a lighting structure, it is necessary to prepare 4% of the fiber-optic cement on the total mass of the composition. It is equally important to lay the threads in the right direction, they are located in a strict one side.

To prepare literon with your own hands, it is important to prepare several components:

purified water;
cement mixture with the addition of fine aggregate;
fiberglass.

From a technological point of view, the production of luxandes can be represented as follows.

Previously, it is necessary to make a box that is a floating formwork. It moves in the vertical direction, when frozen the bulk of the solution.
The finished box is mounted on the preparatory surface, previously aligned. After that, the prepared mixture is submitted to a small volume in the base of the formwork.
After that, the laying of fiberglass in the already sprinkled concrete mixture, slightly combining the material.
Then it is necessary to wait so that the solution is grabbed, and only after that the following portion is performed.
Pouring is repeated and installed fiberglass. The frequency is repeated until the final fill is filling the formwork.
The dismantling of the formwork and grinding blocks are embarking on the completion of the fill of the last layer.

The production of fine-grained concrete solution is reduced to successively mixing 1 hour cement and 3 hours of sand. As for the water, it is introduced gradually, taking into account the final mass of cement. But the total volume of water should not exceed 50% of the entire composition. After that, specialized components contribute, plasticizers, in accordance with the recommendations of the manufacturer's company.

After completing the formation of a transparent concrete, the final grinding is beginning. For this purpose, a platform is carried out. It is carried out 3 days after installing the formwork. In conditions of low humidity, the manufactured blocks are withstanding 5 days.

Litrakon is a common modern material, characterized not only with an impeccable style and appearance, but also exceptional technical characteristics.
