No more or less large concrete design costs without a reinforcing frame. An ordinary was the use of round metal rolling for these purposes. And the industry does not stand still and manufacturers actively promote its composite analogue, namely - fiberglass fittings.

Interstate Standard 31938-2012 regulates the general technical conditions for polymer reinforcing products. The material is a solid round-section rods consisting of two or more components: bases, fillers and binding. For fiberglass it:

• Staple glass fiber, known to each builder as an excellent insulation and reinforcing element.
• Polyamide fiber filler, a high degree of tensile strength and a break.
• Polymeric thermosetting resins (epoxy, vinyl-essential and others).

Composite fittings are made by rods with a cross section of 4-18 mm. The product is cut and packaged either into six-meter ligaments or bays (length - up to 100 m). Buyers are offered 2 types of profile:

1. Periodic - the riflation is achieved by the spiral winding of the rod with fiberglass thin harness. A layer of polymer resin is applied on top to protect the material.

2. Conditional and smooth - finished products are subjected to sprinkling with quartz sand shallow fraction to improve adhesive properties with concrete composition.

The main purpose is the reinforcement of standard and pre-stressed structures that are operated in aggressive environments. But since the melting point of synthetic binders begins approximately from +120 ° C, and burning - from +500 ° C, the erected buildings must meet the requirements of fire resistance according to GOST 30247.0-94, as well as the conditions of fire-resistance specified in GOST 30403-2012.

Fiberglass is used in the following areas:

• Erecting enclosing structures in low-rise construction: the foundation of the pile, ribbon or wood-type, multilayer or monolithic walls made of concrete, bricks, cellular concrete blocks, overlappings and partitions.
• Arrangement of roadbed, sidewalks, sleepers.
• Strengthening screed, industrial floors, flooring, bridge structures.
• Production of shaped products, concrete.
• Formation of frames for greenhouses, small hangars, shield plants.

Companies engaged in the construction of houses from wood and wood materials (OSP or chipboard, arbolit), actively use fiberglass reinforcement for fastening of agrees, intersection points, etc. This is due to the fact that metal products are rust with time, ugly drips appear, it is possible to weaken fasteners and ligaments.

The scheme of the formation of the reinforcing frame from the composite is identical to the rules for working with metal rolled products. The main task is one - enhance the foundation, floor or wall in the maximum tensile or bending voltage area. The horizontal part is closer to the design surface with a minimum step between the "layers" to 50 cm, and the transverse and vertical reference elements are mounted with an interval of at least 30 cm.

Advantages and disadvantages

We list the advantages of the glassomposit:

1. Small weight. The composite rod with a diameter of 8 mm weighs 0.07 kg / mongo meter, and the metal rod of the same section is 0.395 kg / pm.

2. Dielectric properties. The material is inert with respect to radio waves and magnetic fields, does not conduct electricity. It is due to this quality it is used to build special purposes: laboratories, medical centers, testing complexes.

3. Chemical resistance. Products are characterized by inertia to aggressive compounds of sour and alkaline type (concrete milk, solvents, bitumen, sea water, salt formulations). It is used in localities where the soil is characterized by high acidity or alkalinity. Foundation, piles and other similar designs will retain the main properties even with surface damage to the concrete part.

4. Corrosion resistance. Not subject to oxidation, thermosetting resins do not interact with water.

5. The temperature expansion index of the glasskomposit is similar to the similar indicator of cement concrete, which eliminates the risk of stratification with sharp drops of temperature.

6. Simplicity of transportation and installation. Packed in binders of rods or collapsed by bays. The weight of the packaging does not exceed 500 kg, so you can use small cargo transport or passenger cars with low load capacity for transportation. For installation used knitting wire or special plastic clamps.

And now you will get acquainted with the other side of the "Medals":

1. Temperature limits of the application of the glass complex - from -10 to +120 ° C. At minus temperatures, the valve becomes fragile, easily breaks under loads.

2. The modular elastic index does not exceed 55,000 MPa. For comparison, the similar steel coefficient is 200,000. Such a low indicator for the composite means that the rod does not work on stretching. As a result, the appearance of defects on a concrete structure (bundle, cracks).

3. During the fill of the concrete, fiberglass products demonstrate poor stability, the construction is rolled, bends.

4. Plastic clamps are used for bonds of crosshair and places of overlap. In terms of reliability, they are seriously inferior to knitting wire and welding.

5. Corners, curvilinear areas, rod output points for subsequent bundles with a wall, a column is being worked with rolled metal. Grokromamposite for these purposes is not categorically recommended.

6. High value material. If a steel rod with a diameter of 88 mm will cost 8 rubles / a running meter, then the price of fiberglass fittings - 14 rubles. The difference is not too big, but the volume of purchases begins from 200 m or more.

Cost in Moscow

Reviews of designers' specialists are unequivocal: the use of glass accommodation should be limited exclusively to low-rise construction.

Fiberglass and metal comparison

Grokromamposite is positioned as an alternative to metal. We will perform a comparative characteristic:

1. Deformational and physical and mechanical properties.

Based on the table, the glasskeeper works worse for stretching and does not stand the loads that metal. But at the same time, the first type of reinforcement, in contrast to the steelkeeping, does not create "cold bridges".

2. Reactivity.

Metal products are afraid of moisture in any form, as it contributes to corrosion of products and its splitting. The material withstands any minus temperatures without losing the main properties, and the fire frames are not scary - the melting point of the steel begins from +1400 ° C.

Fiberglass does not react with water, salt, alkaline and acid solutions, there is no interaction with such aggressive compositions, such as bitumen, solvents, and the like. However, with a decrease in temperature below -10 or -15 ° C, the products becomes fragile on the break. Grokomposit refers to the combustibility group G2 (moderately combustible) and the fire may create an additional focus of ignition.

3. Safety.

Steel is a material, which contains such volatile impurities as formaldehyde, toluene and others, so it is unreasonable to talk about the discharge of harmful substances. What can not be said about the glass survey. Binding thermosetting resins are synthetic polymer compositions in which various toxic components are present, including phenol, benzene, well-known formaldehyde and so on. Therefore, fiberglass does not apply to the category of eco-friendly goods.

Another point: Metal fittings tested by time and accumulated a great experience of its use, there are real reviews. The advantages and disadvantages have become perfectly known, methods of overcoming the latter have been developed. The confirmed service life is an average of 30-40 years, the same cannot be said about the glass survey. Manufacturers argue that their material can be stopped not less.

The conclusion from the foregoing confirms the opinion of the specialists: the reinforcing rolling leads almost in all parameters and replaced it into fiberglass is irrational.

Opinions of people

"When developing a project of a small cottage, the architect offered to use fiberglass on the belt foundation. I heard a little about this material, on the forums on the Internet most often about it is negative. First of all, due to the lack of methods for calculating and clear standards for the replacement of metal on the composite. The developer convinced me in the appropriateness of such a decision. Reviews can be different, but it is based on the appropriate recommendations of the official manufacturer. The document contained basic instructions: the replacement is not at equal strength, and in the diameter in the ratio of 1 to 4. The house was rebuilt for half a year, there are no signs on the foundation. "

Yaroslav Lehehov, Voronezh.

"The house of foam blocks on technology is reinforced every four rows. You can use both metal and fiberglass composite. I stopped the choice on the latter. According to reviews, such fittings are easily mounted, there are no difficulties with welding or transportation. Working with it is very simple and fast, time costs are reduced substantially. "

Vladimir Katasonov, Nizhny Novgorod.

"For the foundation under the frame bath with insulation, I wanted to choose new-fashioned rods, but the neighbor engineer criticized my positive opinion about the product in the fluff and dust. According to his deep conviction, fiberglass in concrete is solid flaws at a minimum of advantages. If the physical properties of the metal are similar to the concrete component, then the composite is very difficult to make working with a cement-sandy mixture. Because of this problem, negative reviews appear, so it used it for an anchoring of multilayer walls. It also has low thermal conductivity. "

Anton Boldovsky, St. Petersburg.

"When the log house was built, for copiers and places of compounds instead of metal used fiberglass fittings. The remnants folded in the barn, a year later they were useful. Under the brick fence poured a small ribbon, and for the reinforcement made a full-fledged frame from the composite. The disadvantages of the material in the form of a low stretching coefficient did not prevent me from raising a good durable fence, which has been served for about three years. "

Evgeny Korvorgin, Moscow.

Reinforcement of concrete monolithic structures by plastic materials is becoming more widely used in construction. This is explained by such operational qualities as high strength, durability and absence of corrosion. The latter circumstance is particularly important in the construction of hydraulic structures, bridges and foundation grounds.

Building materials manufacturers produce 5 types of composite plastic reinforcement:

• glass-composite or fiberglass - ASK;
• carbonate - AUC;
• basaltasomposite - ABK;
• aRADODOMPOSITE - AAC;
• combined - acc.

From the name it can be understood which material is the basic basis for the manufacture of plastic reinforcement.

General description and technology of manufacturing

Due to its low cost and good operational qualities, fiberglass fittings were the greatest distribution. Its strength is slightly lower than that of other composites, but the cost reduction justifies its application. For its manufacture use:

• staple fiberglass;
• epoxy thermosetting resins as a binder;
• special polymer additives to increase the strength and improvement of other characteristics.

Composite fiberglass fittings for the foundation can have a smooth or corrugated surface. According to the manufacturing technology, originally of the fiberglass form harnesses of the required diameter and soaked with their epoxy resin. After, to obtain a corrugated alternating section, the surface of a smooth rod is turned on the helix with a cord, which is also woven from fiberglass. Then the obtained billets are polymerized into the furnace at high temperature and, after cooling, cut into direct segments or unwound into the bay.

Specifications

The production of the periodic profile and the technical characteristics of fiberglass fittings are governed by GOST 31938-2012. Standard determines:

• types of plastic reinforcement depending on the materials used;
• nominal diameters ranging from 4 to 32 mm;
• the length of the straight rods from 0.5 to 12 meters;
• the possibility of supplying materials in bays with diameter to 8 mm inclusive;
• marking and symbols;
• methods of quality control;
• rules for storage and transportation.

The weight of the material depends on the magnitude of the cross section and can be in the range from 0.02 to 0.42 kg / m.

Data on the limiting strength and elasticity given in GOST show that these parameters exceed the characteristics of steel rolled with the same diameters. This allows the use of polymeric reinforcement into specially responsible structures or, if necessary, decrease the cross sections of reinforcing materials.

Area and method of application

Plastic fittings is a modern alternative to metallic rolled. The same form of rods allows its use according to the technology is similar to steel. The reinforcement frame of composite plastic fittings is formed as a flat mesh or spatial design designed to enhance and increase the strength of reinforced concrete monoliths.

Polymer reinforcing materials are used in the construction of roads, bridges, hydraulic structures, columns, walls, overlaps, foundations and other monolithic structures.

The main load falls on the longitudinal rods of the design. They have a greater section and are located at a distance of no more than 300 mm from each other. Vertical and transverse elements may be at a distance of 0.5-0.8 m. The connection of individual rods in the places of intersections is carried out using polymer screeds or knitting wires. The docking of individual rods on one horizontal line is carried out by Van.

Advantages of plastic fittings

When composing composite rods with metal (we have already performed comparison in this article), a number of advantages and minuses of plastic fittings are clearly defined. These include:

• reducing the weight of the reinforcement frame 5-7 times;
• higher strength to reduce the diameter of the rods;
• corrosion resistance and chemicals in the composition of concrete;
• simple installation and high speed assembly of reinforcing frames;
• simplified technology for creating round and oval designs;
• excellent dielectric and thermal insulation properties;
• ease of transportation.

In addition, it should be noted the unlimited length of the rods in the materials supplied in the bays, as well as a simple cutting of the blanks of the required length.

Fiberglass-based fittings are 20-30% inferior by strength to other composites, but significantly cheaper. Therefore, such a material takes higher demand in construction.

disadvantages

Among the main mines of composite reinforcing materials, specialists call:

• low limit use temperature not exceeding 60-70 ° C;
• weak mechanical stability during transverse loads;
• the impossibility of bending with a small angle of rounding and the need to use special elements.

It should be noted the absence of a regulatory framework for the use of polymers for reinforcing concrete and, often, unreliable technical data from the material manufacturer. This makes it difficult to carry out the calculations and forces the collection of structures with a margin of strength.

Foundation Reinforcement Technology Composite Materials

The small weight of plastic reinforcement for the foundation simplifies the process of assembling the reinforcement frame of any design. At the same time, due to the increased strength of the material, the diameter of the cross section is taken to one number less than for metal analogs.

The technological process of installing concrete monolithic structures with the use of polymer rods consists of the following steps:

1. installing the formwork and mark of the fill level of the concrete mix;
2. assembly and installation of the reinforcing frame;
3. pouring concrete into formwork;
4. removing formwork shields.

Work on the installation of reinforced monolithic structures must be performed in accordance with the project decisions adopted. The deck configuration must fully correspond to the size and form of the foundation. As a formwork material, you can use full-time shields of factory manufacture, boards, moisture-resistant faeer or chipboard. For a non-removable formwork, sheet expanded polystyrene foam is most often used.

After assembling and fixing formwork shields, on their inner side, with the help of a water level, the upper limit for the fill of the concrete mixture is made. This will reduce the time of work and will help more evenly distribute concrete.

Spatial reinforcing frame for ribbon foundation

The scheme of the reinforcement of the foundation, styling and diameter of the rods are always indicated in the project. The use of composite reinforcement, especially on the basis of carbon fiber, allows to reduce the diameter of the rods to one size. The laying of the material must accurately comply with the calculated data. The frame assembly is made on a flat site.

Work begins with cutting blanks. For this, the segments of the required length are rewound from the bay and are installed from the stand at an altitude of 35-50 mm above the support pillow or soil. After that, transverse jumpers are stacked, according to the drawing, and in places of intersections are bound by wire or tie. Thus, the lower row of spatial reinforcement framework will be collected.

At the next stage, it is necessary to assemble the grille, completely similar to the first, lay it on top and then cut the vertical stand of the design length. The first stand is attached to the corner of flat lattices, the second - on the adjacent intersection, as a result, a spatial structure is as gradually formed. If the horizontal series is greater, then the second lattice is fixed at the desired height, and then the next one is fixed. The vertical stand in this case is one whole segment.

When assembling the frame, it is necessary to remember that the ends of the reinforcement rods must be from formwork at a distance of 35-50 mm. This will create a protective layer of concrete and increase the operational period of construction. To this end, it is very convenient to use special plastic locks.

At the bottom of the trench, it is necessary to pour a sand-chicken pillow and a good tamper. After this layer of sand, it is recommended to cover with geotextiles or waterproofing material. This will prevent the flow of moisture to concrete and the germination of weed plants.

Horizontal reinforcement of slab foundations

When pouring the foundation bases of the plate type, use horizontal reinforcement technology. Its main feature is the lack of rotary and adjoining sites. Usually these are two grids located over each other from long straight rods and vertical racks.

All works are performed at the place. First, according to the project drawing, the lower mesh fit, and the top is stacked on top of it. After that, vertical racks are installed, as described for ribbon structures. The lower grid must be installed on the stand.

Concrete Pouring on Plastic Armature Frame

Technologically, the fill of the concrete mix is \u200b\u200bno different from the work when using steel reinforcement. However, given the smaller strength of the material with lateral radial exposure, the seal of the vibrator should be made carefully not to disturb the integrity of plastic rods.

When building any building requires a foundation. So that it was stronger, fittings are inserted into the concrete. Previously, it was made exclusively from the metal. Modern technologies make it possible to produce fittings from the composite. It has its advantages and cons, and therefore before using it in the construction of a bath, you should carefully study the features.

Features of the material

Armature that is made from various composites, has been applied both in private and in capital construction

Armature from the composite is two species depending on the material of the manufacture. It is made of fiberglass or basalt fiber. The latter is much more expensive, although in its properties slightly exceeds the quality of fiberglass rods.

The peculiarity of composite reinforcement is that it consists of two layers - internal and external. The inner part is the core of the fibers located in parallel. These fibers are combined with an epoxy or polyester resin composite. It is from the core depends on the characteristics of the reinforcement.

On the core in the form of a spiral of the wolves, which are also combined with a composite. This part is responsible for adhesion with concrete solution.

Since the composite material does not have sufficient bending strength, it is not suitable for knitting when laying steel rods. To do this, it is better to use plastic clamps.

Pros and cons

The fastening of carbonistic spinners is carried out by special clamps, there is no need to use welding for fastening

The advantages of composite reinforcement include:

• low weight;
• the cost is lower than that of metallic;
• strength;
• resistance to the effects of aggressive media;
• excellent thermal insulation properties, which is the main advantage in the construction of a bath;
• is not a conductor, and therefore does not create interference for radio waves;
• service life can be 80 years;
• the reinforcement is sold in the bays, and therefore the length of the rod is unlimited.

And yet there are composite reinforcement and disadvantages:

• it cannot be operated at temperatures above 200 ° C;
• not too elastic. However, the last drawback is important only in the construction of high-altitude houses. In the foundation of the bath, the elasticity does not play any role.

If you are not going to heat the foundation of the bath to too high temperatures, then the best choice is to use precisely composite fittings. Durable and lightweight material that can be cut into pieces of any length, has excellent reinforcing properties.

The main advantages of composite reinforcement are in its low weight, high tensile strength, high chemical and anti-corrosion resistance, low thermal conductivity, low thermal expansion coefficient, and in the fact that it is a dielectric. High tensile strength, significantly exceeding a similar parameter in steel reinforcement with an equal diameter, allows to use composite reinforcement of a smaller diameter instead of steel.

You can not even imagine how profitable is the use of fiberglass fittings! The economic gain from its use is made up from a number of factors, and not from one difference in the cost of the cost of steel and composite reinforcement.

Do not be lazy to see a complete description of the factors that make up your savings, time, man-hours, electricity, consumables, etc. In the article "Saving from the use of composite fittings"

But it must be remembered that composite reinforcement has substantial minuses. Most Russian manufacturers do not advertise these minuses, although any engineer builder may notice them independently. The main disadvantages of any composite reinforcement are the following:

• the modulus of the elasticity of composite reinforcement is almost 4 times lower than that of steel even with an equal diameter (in other words it is easily bent). For this reason, it can be used in the foundations, road plates, etc., but the use in overlaps requires additional calculations;
• when heated to a temperature of 600 ° C, the compound binding the fibers of the reinforcement is softened so much that the armature completely loses its elasticity. To increase the stability of the structure to fire in the event of a fire - it is required to take additional measures to ensure the structures in which the composite fittings are used;
• composite reinforcement, unlike steel, is impossible to weld with electric welding. The solution is to install on the ends of the reinforcement rods of steel tubes (in factory conditions) to which electric welding can already be used;
• such reinforcement is impossible to give bending directly at the construction site. The solution is to manufacture the reinforcement rods of the required form on production according to the customer's drawings;

Summarize

Despite the fact that all types of composite reinforcement are quite new material in the construction market of Russia. Its use has great prospects. To date, it can be safely used in low-rise construction, in the foundations of various types, in road plates and other similar structures. However, to apply it in high-rise construction, in the structures of bridges, etc. - It is required to take into account its physico-chemical features at the stage of preparing for design.

Curious fact - fittings in the bays!

The main use of reinforcement in low-rise construction is to use it for the reinforcement of foundations. At the same time, steel fittings of class A3, diameters 8, 10, 12 mm are most often used. The weight of 1000 meters of the row steel reinforcement is 400 kg for Ø8mm, 620 kg for Ø10mm, 890 kg for Ø12mm. Theoretically, you can purchase steel reinforcement in the bays (if you find), in this case, later, you will need a special device for re-aligning such reinforcing. Can you transport 1000 meters of such reinforcement on your passenger car to the construction site to reduce shipping costs? And now imagine that the specified fittings can be replaced by a composite smaller diameter, namely 4, 6, 8 mm instead of 8, 10, 12 mm. respectively. The weight of 1000 meters of the shaft composite reinforcement is 20 kg for Ø4mm, 36 kg for Ø6mm, 80 kg for Ø8mm. In addition, it decreased somewhat. Such fittings can be purchased in bays, while the outer diameter of the bay is a little more than 1m. In addition, when unwinding such a bay, composite fittings do not require straightening, as it practically does not have residual deformation. Could you imagine that you can carry the reinforcement required for the construction of a country house or cottage, in the trunk of your own passenger car? And you do not even need help when loading and unloading!

Which appeared on the construction market relatively recently, has both the advantages and disadvantages of which the consumer must be aware. Despite the certificates of manufacturers in the fact that this product is a complete replacement of metal reinforcement, not in all situations, its use can be considered reasonable.

What is the fittings from fiberglass

The so-called composite reinforcement is a rod of fiberglass, around which the carbon filament is wound, serving not only to enhance the design of such a product, but also to ensure its reliable adhesion with concrete solution. The reinforcement of this type has both pros and cons, and its use should be approached very weighted.

Elements for fixing carbon fired reinforcement rods with each other are plastic clamps. It is convenient that the use of welding is not required to connect the elements of such valves, which is undoubtedly a big plus.

Evaluating the feasibility of using fiberglass fittings, it is necessary to consider all the pros and cons of its use in separate situations. This approach will ensure the high efficiency of this material as a means of strengthening building structures for various purposes.

If not to take into account the characteristics of fiberglass reinforcement and not compare them with the parameters of similar products made of metal, it is possible to make a serious damage to the future building design or finishing elements. That is why before proceeding to the choice of elements for the reinforcement of concrete structures, it is necessary to understand, in what cases, the use of certain products is more appropriate.

Main advantages

Among the advantages that are distinguished by carbonate fittings, it is worth highlighting the following.

• An important advantage of fiberglass fittings is its small proportion, which makes it possible to use it for reinforcing lightweight structures from cellular concrete and some other building materials. This allows you to significantly reduce the weight of the structures that are reinforced with its help. Meanwhile, the weight of a conventional concrete structure when using fiberglass reinforcement will decrease insignificant, since the building material itself has an impressive mass.
• Low thermal conductivity also relates to the benefits of fiberglass fittings. When using such reinforcements in concrete structures, cold bridges are not formed (which cannot be said about the reinforcing elements from the metal), which significantly improves their thermal insulation parameters.
• The high flexibility of fiberglass reinforcement allows you to ship it to the customer in the bays, and not sliced \u200b\u200bby individual rods. Thanks to the compact packaging form, it is much easier to transport such fittings, for which you can use the trunk of any passenger car, and this seriously reduces the cost of delivering material to the construction work. The use of reinforcing elements that are shipped by non-chopped rods, and in bays, it also makes it possible to reduce the cost of material by reducing the number of adhesive. This is positively affected by both the strength characteristics of the future concrete design and at its cost, which is especially important when performing construction work.
• Such an advantage of fiberglass reinforcement, as its durability inside the concrete structure, is considered rather controversial. Metal fittings, being in an isolated state, is also not subject to the negative impact of external factors, which ensures the durability of its use.
• Carbon fiber reinforcement is a dielectric material, which is the advantage of products from this material. Conductive electric current Metal fittings are more corrosion, which negatively affects its durability.
• Compared with the reinforcing elements of metal, fiberglass products are not affected by chemically active media. Such an advantage of fiberglass reinforcement is particularly relevant in cases of building structures in winter, when various saline solutions are added to the concrete, accelerating the process of frost.
• As a dielectric, carbon fiber reinforcement does not create radio domain inside the building, unlike metal rods. This advantage is important when there are many reinforcing elements in a concrete structure. Otherwise, the use of composite reinforcement will not become a minus, but will not be so relevant.

There are in fiberglass reinforcement and disadvantages, which should also be aware of its potential consumers.

Most shortcomings

Disadvantages of fiberglass fittings are associated with the following characteristics.

• The minuses of fiberglass reinforcement include, in particular, the fact that it does not withstand the effects of high temperatures. At the same time, it is difficult to present the situation when the reinforcement frame that is inside the concrete can be heated to a temperature of 200 degrees.
• A fairly high cost is a conditional drawback, given the fact that for reinforcing concrete structures, fiberglass fittings of a smaller diameter can be used in comparison with metal products.
• The reinforcement from the carbon fiber is bad. This disadvantage limits its use when creating firming frames for concrete structures. Meanwhile, it is possible to perform bent areas of the reinforcement frame from steel elements, and then increase them with fiberglass rods.
• The fittings made of fiberglass, poorly withstands the load on the break, which is very critical for concrete structures. Accordingly, their enhancing framework must successfully withstand such loads than the fittings made of composite materials cannot boast.
• Unlike a metal reinforcement frame, fiberglass products have less rigidity. Because of this disadvantage, they poorly carry vibration loads arising from their fill with the help of a car mixer. When using such equipment, the reinforcement frame is subjected to significant mechanical loads that can cause its breakdown and violation of the spatial position of its elements, so sufficiently high demands are presented to the stiffness of such concrete structures.

Considering the advantages and disadvantages of fiberglass fittings, it is difficult to say how much it is better or worse than made of metal. In any case, the choice of this material should be approached very reasonably using it to solve those tasks for which it is really intended.

Fiberglass reinforcement

Armature made of composite materials, the rules of laying of which is easy to learn from the relevant video, used in the capital, and in private construction. Since capital construction is carried out by qualified specialists who are familiar with the nuances and the disadvantages of the use of certain building materials, we will focus on the use of such material when erecting private low-rise buildings.

• Armature made of composite materials is successfully used to strengthen the foundation designs of the following types: tapes whose height is greater than the depth of soil freezing, and slab. The use of reinforcement from carbon fiber to strengthen the foundations is only in cases where the structure is erected on a good soil, where concrete bases will not be subjected to loads on the break, which fiberglass elements may simply not withstand.
• With the help of fiberglass reinforcement, the walls of which are made of brick, gas-silicate and other blocks are strengthened. It should be noted that, as a binding element of the walls, composite fittings are very popular among private developers who use it not only to strengthen the masonry of the supporting structures, but also to ensure their bundles with facing partitions.
• This material is actively used for ligament elements of multilayer panels. The structure of the latter includes a layer of insulation and concrete elements, which are binding to each other with fiberglass fittings.
• Due to the fact that the armature of the type under consideration is devoid of such a shortage of corrosion exposure, it is often used to strengthen various hydraulic structures (for example, dams and pools).
• In cases where it is necessary to effectively increase the rigidity of glued wooden beams, they are also strengthened using fiberglass fittings.
• This material is used and in road construction: it is used to strengthen the layer of asphalt web, which is exposed to increased loads during its operation.

Summarizing all of the above, it should be noted that the use of fiberglass fittings can be determined quite effectively if its disadvantages and associated restrictions that are negotiated by the manufacturer.

Can fit the fiberglass replace analogs from metal

Despite the fact that the reinforcement made of composite materials is quite new material in the construction market, you can already find a lot of recommendations (and even video) to use it. Given these recommendations, it can be concluded that it is best to use fiberglass fittings to strengthen the walls that are erected from bricks and building blocks, as well as to communicate bearing walls with interroom partitions.
