What is fiberglass reinforcement made of? The truth is all about fiberglass reinforcement. Scope of application of composite reinforcement

When fiberglass reinforcement was first developed (57 years ago), its cost was much higher compared to steel bars, so the composite material was not widely used. Today the situation has changed, the cost of reinforcing material has decreased, and its advantages are appreciated by construction companies engaged in the construction of facilities in regions with cold climates.

Now fiberglass reinforcement is produced both in the form of threaded rods and in coils. The cross-section of the rods ranges from 4 to 32 mm. Let's take a closer look at the areas in which this type of reinforcement is most often used.

Features and scope of application

Plastic fittings are physical body, which consists of the following elements:

• The main trunk is made of parallel fibers connected to each other using a polymer resin. This element provides the strength characteristics of the reinforcement.
• An outer layer of fibrous material that is wound in a spiral around the main stem plastic fittings. Such winding can be sand sprayed or bidirectional winding.

If we talk about the use of fiberglass reinforcement in construction, today composite materials are widely used for:

• reinforcement of various reinforced concrete structures;
• repair of reinforced concrete and brick surfaces;
• installation of buildings made of lightweight concrete;
• layer-by-layer masonry of walls (flexible connection technology);
• reinforcement of tile, columnar and strip foundations;
• strengthening concrete screeds;
• drainage;
• creation of road surfaces and fences;
• design of seismically resistant reinforcing belts.

In addition, fiberglass reinforcement is used in many other industries, and its characteristics meet all construction requirements and standards, so products of this type are suitable for both private construction and mass production.

Manufacturing technology

Composite reinforcement can be manufactured using one of three technologies:

1. Winding. In this case, winding is performed on specialized equipment. The winding device moves along a rotating mandrel. After several approaches, a complete cylindrical surface is created, which is sent to the oven for heat treatment.
2. Reaching out. First, the fiberglass is unwound from the spools and soaked in resin. After this, the material passes through dies and excess scrap is removed from it. At the same time, the plastic reinforcement bars are given cylindrical shape. After this, the winder manually applies a spiral strand to the workpiece, which is used to increase the adhesion of the material and concrete mortar. In the next step, the fiberglass reinforcement is sent to the oven, where the resin hardens. Once the rods are completely polymerized, they are passed through the broaching mechanism.
3. Handmade. This is the most expensive process for producing plastic fittings, so it is used only for small-scale production. In this case, first a special matrix is ​​prepared, onto which a gelcoat (protective decorative layer) is applied. After this, the fiberglass is cut, soaked in resin and hardeners and placed into a mold. Next, the product undergoes heat treatment and is cut.

The first method of producing plastic reinforcement is considered the cheapest, so products that have been wound are used most often.

In the manufacture of rods of this type, various types of fibers are used.

Types of composite reinforcement

Fiberglass reinforcement can be the most different types, the most famous of them are:

• ASP is a fiberglass reinforcement that is manufactured classical method winding fiberglass. The diameter of the fibers of the product ranges from 13 to 16 microns.
• ABP – basalt-plastic reinforcement. In this case, the main trunk of the product is made of basalt fibers with a diameter of 10 to 16 microns.
• AUP is a carbon fiber reinforcement that uses both fiberglass and thermoplastic. The diameter of the fibers used is up to 20 microns.

Most often, ASP and ABP are used in construction. Carbon fiber reinforcement has reduced mechanical strength, so it is used very rarely. In addition, on sale you can find products from ASPET (a mixture of fiberglass and thermoplastics), ACC (combined reinforcement) and many other varieties.

In addition, fiberglass reinforcement is sold:

• piece rods;
• mesh;
• frames;
• ready-made structures.

In addition, products are classified based on the type of structure for which they are used:

• fittings for housing and communal services;
• installation;
• working;
• distribution

It is also worth paying attention to the properties and characteristics of composite reinforcement.

Technical properties, advantages and disadvantages of plastic reinforcement

When choosing plastic reinforcement to strengthen the foundation, it is worth considering the following characteristics of the products, which in most cases are much better than those of metal analogues:

• The maximum operating temperature is from 60 degrees.
• Tensile strength – no less than 800 MPa (for ASP reinforcement) and no less than 1400 MPa (for AUK type products). For metal, this figure barely reaches 370 MPa.
• Relative elongation – 2.2%.
• Since this material belongs to the first group in terms of chemical resistance, fiberglass reinforcement can be used in aggressive or alkaline environments.
• Density is 1.9 kg/m 3, so ASP weighs 4 times less than a steel frame.
• Easy to transport.
• Low thermal conductivity.
• Long service life (more than 80 years).
• Corrosion resistance.

In addition, when using fiberglass reinforcement, you don’t have to be afraid that it will jam the signal cellular communication or a radiotelephone, since this material is a dielectric.

Fiberglass is also resistant to low temperatures, but at extremely high temperatures the material begins to melt. However, in this case you will have to heat the surface to at least 200 degrees.

Interesting! Builders never have a question about how to cut fiberglass reinforcement, since it lends itself well to processing with a regular grinder.

The most obvious disadvantage of composite reinforcement is its instability. If you want to prepare it separately from the formwork, it may “skew”, so it is better to install the reinforced belt directly into the formwork.

If we talk about cost, then basalt-plastic reinforcement will cost about 6 rubles per linear meter, and fiberglass reinforcement – ​​from 9 rubles. If we compare it with steel rods, costing from 21 rubles per meter, it becomes obvious that today fiberglass rods not only do not cost money, but also cost almost half as much as metal rods.

However, you should not rejoice ahead of time, because there are many unscrupulous manufacturers on the market who offer customers low-quality products.

What to look for when purchasing fiberglass reinforcement

To distinguish a low-quality product, pay attention to the following nuances:

• Composite reinforcement must be manufactured in accordance with technological process. If the product has an uneven color with sharp transitions, then such rods are not suitable for construction.
• If the rods Brown, then this suggests that on final stage manufacturing, the rods have not undergone the necessary heat treatment, or temperature regime was not followed correctly. Such products must be rejected in production.
• If you notice that the rods have a greenish tint, then such products are also not worth buying; they will have a very low modulus of elasticity for fracture. This occurs due to the fiberglass processing temperature being too low.

Color is the main indicator of the quality of the reinforcement, so make sure that the shade of the rods does not differ.

It is also necessary to select the correct fasteners for the fiberglass armored belt. Plastic holders are best suited for this purpose:

• Horizontal (for concrete slabs and floors) allow you to create a layer 25-50 mm high.
• Vertical (for wall surfaces) – layer thickness 15-45 cm.

Fiberglass reinforcement- This is a modern development that makes foundation and concrete work significantly easier. The method is new, so when choosing, it is important to know its characteristics, advantages and disadvantages in comparison with metal fittings.

AKS - what is it, its structure and appearance

Composite reinforcement is a round rod with knurled stiffening ribs. Made from fiberglass. Available in various sections. Its diameter, depending on the required strength of the products, can vary from 4 mm to 18 mm. Workpieces can be cut into lengths up to 12 m.

For ease of transportation, twisting of the reinforcement is used if its cross-section is up to 10 mm in diameter. Additional strength is achieved by using continuous fiberglass fiber production. Foreign manufacturers call this method polymer equipment.

In our documents, the fiberglass reinforcing part is designated by the abbreviation AKS. Fiberglass reinforcement is made of 2 main parts:

• the main part is the central barrel. It is made of parallel fiberglass threads. A polymer resin is used to connect them. This device gives the product additional strength;
• external coils or sprinkling for better joining with concrete. They are applied in the form of several spirals along the entire length of the main trunk. There are two methods for making coils: powder coating and bidirectional winding of fins. Composite reinforcement is produced in various types central rod. A pigtail made of carbon fiber is one of the types of this part.

Physical properties and materials used in the production of reinforcing products

The main characteristics were obtained after a number of scientific research and implementation the latest developments. Some properties allow it to be used for reinforcement in residential and industrial construction:

• light weight of products - steel reinforcement is an order of magnitude heavier (9 times);
• not subject to destruction from corrosion, exposure to acids, alkalis. According to this indicator, metal fittings are inferior by 10 points;
• low level of thermal conductivity. When arranging foundations and floor slabs, the possibility of thermal insulation failure due to cold bridges is reduced to 0.
• light and flexible– this quality simplifies its delivery and work;
• does not conduct electricity, is not affected by stray currents;
• thanks to plasticity takes any shape, no welding or cutting machines required.

Thanks to these characteristics, reinforcing the foundation with fiberglass reinforcement becomes justified both in production and economic terms. Much in this matter is decided by the material used for the production of ASP. The industry produces composite non-metallic reinforcement from several types of modern plastics. They have a base made of the following materials:

1. Fiberglass.
2. Carbon fiber.
3. Basalt-plastic.
4. Made from aramid.
5. Material created on the basis of glass-reinforced polyethylene terephthalate.

The price of some materials does not allow their use in mass quantities. For this reason, 2 types of materials are most popular. These are fiberglass and basalt plastic products. The main trunk is woven from many strands of material. They are connected using thermoactive synthetic resins.

To securely connect the rod, either sand coating is applied, or the trunk is wrapped around several turns running in a spiral. When using fiberglass reinforcement, one should take into account its property of slight stretching in a concrete product. In this case, there will be very little contact with the concrete and separation of the coils or abrasive coating will occur.

Products made of basalt plastic do not have a reliable connection with concrete. The best fixation is provided by coils made of carbon fiber, applied to the fiberglass main barrel. In this case, the load is evenly distributed over the entire part and the rod is normally fixed to the concrete mass.

Advantages and disadvantages of use

Reviews from builders allow us to recognize the following main advantages:

• light weight of products It not only makes the work of workers easier, but also makes the structures quite light. Therefore, it is used for cellular concrete and other materials that reduce the weight of the structure while maintaining a high level of reliability and strength;
• metal, capable pass cold through cold bridges. The use of fiberglass reinforcement eliminates this possibility; this advantage is especially important in monolithic construction of buildings;
• consumption decreases material when packaging it in coils. The lashes are produced in lengths of 12 meters, which allows for more economical cutting. This point is especially important in private construction, when every ruble spent is scrupulously calculated;
• increases economic component, the possibility of linking without overlaps and using welding work;
• capable of serving for a long time and not losing its properties, but metal, laid in concrete slab also does not decompose;
• dielectric qualities They provide a guarantee of safe living in the building, but this dignity is debatable. Concrete itself is a dielectric;
• high level resistance to chemicals is important when performing foundation work at low temperatures. At this time, various additives are added to the concrete;
• Does not interfere with the passage of radio waves. This quality is especially important in monolithic construction; metal fittings interfere with the normal operation of mobile communications and the passage of radio signals. The use of composite reinforcement can reduce the level of radio interference in the building.

These products also have disadvantages. A specialist using this material can easily name them:

• Reinforcing fiberglass(asp) exceeds the cost of steel reinforcement. But this disadvantage is easily offset by the possibility of using thinner reinforcement for a similar type of work;
• subject to deformation and destruction at high temperatures ah, but the likelihood of such an impact inside concrete is unrealistic;
• if used fiberglass reinforcement for the foundation with many turns, it is not possible to bend the parts for bending, but the problem is easily solved. It is enough to take a piece of steel bar, bend it under the right angle and tie with the main lash;
• one of the main disadvantages are low elasticity when the rod breaks. In this case, fiberglass reinforcement is inferior to steel, but it works better in tension. Due to its low fracture resistance, its use in capital construction somewhat limited;
• using you need to be extremely careful when using the foundation and pouring concrete from a mixer. Glass reinforcement cannot be laid in a rigid frame and when high pressure its integrity may be compromised. Composite mesh is The best decision question.

How to knit fiberglass reinforcement, but easier than metal. This does not require the use of different hooks. It is tied together with self-tightening plastic clamps. The operation is simple and requires a minimum of knowledge and tools.

Having considered the advantages and disadvantages, it is impossible to unequivocally answer the question which is better - lightweight plastic or hard steel. Only construction engineers can do this.

Scope of use and main types of reinforcing rods

These products are divided not only by their appearance and the method of applying stiffeners. The main classification is the scope of use of rods:

• working;
• distribution;
• installation;
• produced for strengthening concrete products and structures.

Production has been established various products, depending on the assigned tasks for reinforcement in construction:

• separate, different in size, lashes;
• reinforcing mesh;
• Depending on the size, frames of various designs and dimensions are produced.

With a short period of use, composite reinforcement is used by various construction organizations. Used for making drainage wells, concrete walls, reinforcement is being made strip foundation fiberglass reinforcement. Widely used in road construction.

With its help, they reinforce the canvas, embankments, the bases of highways, and well strengthen the brick and block masonry of walls. This material is widely used in private households and for furnishing various greenhouses and a greenhouse, for reinforcing a small foundation. Such structures are lightweight, easy to install and disassemble.

Adding to the popularity of the material is its ease of transportation and operation. For delivery you do not need to order a truck; delivery can be done in a passenger car.

Analysis and comparison of the main parameters of two types of reinforcing materials

You can get a complete and reasoned answer to the question of which fittings are better by carefully comparing the main parameters of plastic and metal fittings.

According to the resistance of plastic to corrosion and chemicals it is preferable to steel. This material is also better in terms of electrical safety and not obstructing radio waves into the room. In general, no specialist can decide which material is preferable.

Only by completing other elements of the building and comparing it with the calculation of the structure using steel reinforcement can you get a reasoned answer. And only after this we reinforce the building parts and concrete products calmly and with confidence in the chosen material.

In conclusion, it should be noted.

Experience with this type of reinforcement appeared in construction several decades ago. Despite this, the method has significantly strengthened in the market of materials for concrete work. The scope of application of fiberglass reinforcement is quite wide.

These include the production of greenhouses on peasant farmsteads, low-rise construction, and use in the construction of highways. In each of these areas, the consumer receives a reliable and lightweight design with minimum costs strength and means.

Composite reinforcement, which appeared not so long ago, has already managed to win the lion's share of the construction market. In our article we will talk about what it consists of, how it differs from traditional metal and where it is used, and also consider the most common myths.

Composite reinforcement was invented more than 30 years ago, but has only become widespread in the last few years. Thanks to its technical and operational characteristics, such a material is quite capable of competing with classic steel reinforcing rods.

Composite reinforcement appearance resembles steel, but it is made of fibers impregnated with special binder-hardening compounds. During the manufacturing process, ribs are formed on the rods or a sand coating is sprayed to improve adhesion to concrete.

Several types of composite fibers are used for the production of reinforcement:

1. Fiberglass with the addition of thermosetting resins - fiberglass reinforcement.
2. Basalt fiber with the addition of resins is basalt-plastic reinforcement.
3. Carbon fiber (carbon) - carbon fiber reinforcement.
4. Kevlar thread from DuPont - Kevlar reinforcement.

The last two types are used extremely rarely and mainly abroad. Compositions of hydrocarbon plastics and Kevlar were developed for use in the space and military industries, so they are characterized by both high strength and exorbitant prices.

Civil engineering gives preference to fiberglass reinforcement, which is optimal in cost and range of applications.

Advantages and disadvantages of composite reinforcement

The most vulnerable point of reinforced concrete products is the reinforcing metal inserts, which are susceptible to corrosion. Treating with primers or using alloys does not completely solve the problem - the metal sooner or later rusts, destroying the concrete. Fiberglass reinforcement is not exposed to aggressive environments, which is just one of the many advantages:

1. Tensile strength indicators exceed those of metal by almost three times.
2. In terms of equal strength, composite reinforcement weighs 9-11 times less.
3. The material is not only inexpensive, but also allows you to significantly save on loading and transportation.
4. Unlike metal, it does not form cold bridges, reducing heat loss.
5. Durability and resistance to temperature changes.
6. It has a coefficient of thermal expansion similar to concrete, which reduces the risk of defects and cracks.
7. Completely dielectric and radiotransparent.
8. It can be produced both in the form of rods and by winding into coils.

Tests also show the other side of the coin - the disadvantages of composite reinforcement:

1. The low modulus of elasticity requires additional calculations when using such reinforcement in floor slabs.
2. Low fire resistance is due to the fact that composites simply melt when exposed to high temperatures, turning into liquid.
3. Inability to use welding.
4. Inability to bend finished reinforcement on site.

It should be noted that all negative nuances are successfully resolved by manufacturers and design engineers: when constructing structures with high loads, special surveys and calculations are carried out, to increase heat resistance, additional processing of concrete compositions and the reinforcement itself is used, all curved parts are manufactured in factories according to designs.

Comparative characteristics of metal and composite reinforcement

Subject to compliance with building codes, composite reinforcement can replace metal reinforcement in all areas of application:

1. Cottage construction: any types of foundations and flexible connections for walls.
2. Concrete structures in industrial buildings and multi-storey buildings.
3. Production of heavy and light concrete.
4. Layered brickwork various types.
5. Bank protection and construction of coastal structures (not afraid of contact with water).
6. Laying the road surface (increases service life by a third).
7. Creation of earthquake-resistant belts (recommended for use in areas of high vibrations).
8. Construction of monolithic buildings using permanent formwork.
9. Electrification (lighting poles and power lines).
10. Production of railway sleepers.

The characteristics of composite reinforcement can be most clearly presented in comparison with metal analogues:

When assessing the feasibility of purchasing composite reinforcement and comparing its cost with metal, many pay attention only to the price linear meter. The ROCKBAR company (manufacturer of fiberglass reinforcement) together with the University of Sheffield (UK) conducted comparative tests on the tensile strength and strength of materials, which resulted in a table of equal strength replacement:

Note: prices are taken from the official websites of manufacturers; in retail chains they may vary slightly.

Simple calculations show that savings when purchasing reinforcement made of composite materials can be up to 2 times compared to metal. Don't forget about other expense items:

• savings on delivery due to lightness and compactness;
• saving on loading and unloading - no need to hire workers;
• savings on consumables— fiberglass can be cut with wire cutters or bolt cutters;
• savings on scraps - reinforcement in coils is cut to the required sizes without waste.

Beware: unscrupulous manufacturers

The introduction of innovations in the building materials market is always difficult. Composite reinforcement is no exception. On the one hand, many large and small manufacturers have appeared. On the other hand, all factories operate according to their own technical specifications and try to lure the buyer with cunning tricks. Let's look at the most common myths.

Myth: Our products are better because we add secret ingredients (which also add an unusually vibrant color).

Fact: Pigmentation does not affect durability; its only advantage is aesthetics. Moreover, an incorrectly selected pigment can worsen operational properties. All specifications must be documented in test reports.

Myth: The more often the winding ribs are located, the stronger the reinforcement.

Fact: Wrapping ribs serve to increase grip concrete composition and do not in any way affect the rupture, strength and compression of reinforcement. The only exception is a sand coating, which evenly distributes the load along the entire length of the rod.

Myth: Fiberglass reinforcement can be broken by hand, what strength can we talk about?

Fact: Reinforcement made of composite materials works on longitudinal rather than transverse loads.

Unfortunately, there are no GOST standards for composite reinforcement yet. Therefore, choose products from trusted manufacturers, ask the seller for certificates and test reports, compare them with the indicators given above and do not be fooled by the temptingly low cost.

Olga Danyushkina, rmnt.ru

Fiberglass reinforcement is a building material that is made from glass roving, connected using an epoxy compound based on thermoactive resins. The main feature is lightness; the mass per unit volume is only 2g/mm³. Working with fiberglass reinforcement is more convenient and economically feasible than working with metal reinforcement. Essentially required less costs for logistics and directly during reinforcement.

In addition, due to the fact that fiberglass does not react to an aggressive environment, the reinforcement therefore protects concrete from premature destruction, thereby increasing the service life of the object. Fiberglass reinforcement reacts to temperature changes similarly to concrete, which also has a good effect on the strength of the structure.

The strength of fiberglass compared to metal is 2.5 times higher. At the same time, the thermal conductivity index is 100 times lower than the thermal conductivity index of steel. Therefore, a structure that is reinforced with fiberglass does not freeze (does not form “cold bridges”) and an object built using fiberglass will be warmer than a building based on metal fittings. This allows you to reduce heating costs, and therefore the material is actively used in the construction of modern energy-efficient buildings.

Another undeniable advantage that may be of interest to builders is the fact that fiberglass is a surprisingly durable material, which for 100 years after installation does not require additional repair work. This is what fiberglass reinforcement for foundations is famous for.

Fiberglass reinforcement has found its application in many areas of industry, construction, utilities:

• in construction, it is used in the construction of civil and industrial construction projects as a basis for foundations, floors, beams, as well as in the construction of earthquake-resistant belts;
• In the construction and repair of roads, reinforcement is used in the construction of embankments, road surfaces, in the construction of bridges and highway barriers. It is resistant to the effects of reagents that are applied to road surfaces (for example, de-icing reagents), so it can be used both in Moscow and in colder regions.

Fiberglass reinforcement will be an ideal basis for concrete and brick structures. It is used in the creation of supports for power lines and lighting, in the construction of road, sidewalk and fence slabs, as well as in the installation of sleepers on railway tracks. Reinforcement for floors, where a mesh of reinforcement is used, even together with metal, has become widely used.

Fiberglass is applicable in such building structures How monolithic foundation and foam concrete. It is also actively used in the creation of structures that must have increased resistance to chemicals, for example:

• during the construction of storage facilities for chemical waste and components;
• when installing sewerage systems, water pipelines, land reclamation systems;
• during the construction of port facilities and during the strengthening of coastlines.

Despite the uniqueness of the product, the price of fiberglass reinforcement in Moscow, which is indicated on our website, is available material both for construction organizations and individuals. Its cost is 40-50% lower than the cost of steel reinforcement, which allows you to significantly reduce costs and at the same time improve the quality of constructed objects. In general, composite reinforcement can be called one of the most reliable and efficient building materials our time.

This reinforcement is made from straight strands of glass or basalt fibers (ASP and ABP, respectively), which are collected into a bundle, impregnated with a thermosetting polymer binder, molded, heated (polymerized) and cooled. The result is a monolithic rod of high strength, which, according to test results, is 3 times higher than the tensile strength of steel, and the weight, in an equal strength ratio, is 9 times less.

Standardly manufactured in the form of rods of any length, at the request of the customer. With a diameter of up to 8 mm inclusive, it can be manufactured in the form of coils (coils) containing 100 meters of reinforcement. dimensions coils: height – up to 8 cm, diameter – up to 1 meter.

release form

With a diameter of 10 mm and 12 mm, it can be manufactured in the form of coils (coil fittings) having a length of 50 meters. Overall dimensions of the coil: height – up to 5 cm, diameter – up to 1.5 meters.

By agreement with the customer, it is possible to produce rods and coils of any length.
Can be manufactured with a smooth, construction, periodic profile:

• ASP-ABP of periodic profile, used instead of steel reinforcement of class A-III (A-400);
• ASP-ABP with a smooth profile is used instead of steel reinforcement of class A-I (A-240).

Fiberglass reinforcement is becoming more and more popular and its use is becoming more and more relevant every year, because it is a complete replacement for traditional steel rods of different grades. High strength indicators, optimal performance properties, small specific gravity and low price are factors that determine the popularity of the use of non-metallic reinforcing elements in all areas of construction.

The development of composite reinforcement was carried out back in the last century, but it became expedient to produce and use it only recently.

This was facilitated by the availability of raw materials and the introduction of new technologies into the manufacturing process. Often such products are called fiberglass or basalt plastic.

Basically, different definitions are given due to the difference in combinations of raw materials used. But this does not affect the quality and durability of the products. It differs from its steel counterparts in appearance.

Composition and features

The material is a structural rod similar to steel rebar, but made from the following components:

- glass;

- basalt;

— carbon;

- aramid;

- polymer additives.

Glass products light color with a yellowish tint. Black basalt and carbon rods. Periodic section, as in metal products, ensures the strength of the reinforced concrete structure. Some manufacturers include colored pigments in their composition. This fact does not affect the properties and characteristics in any way.

Types of composite reinforcement

The classification of types of composite reinforcement directly depends on the main component in the composition.

ABP (basalt product) It is produced using basalt fibers and resins of organic origin, which act as a binding element. A distinctive quality of the species is its resistance to aggressive substances and environments (alkalies, salts, gases).

ASP (fiberglass product) obtained by mixing fiberglass and thermosetting resins. The advantage of this type is considered to be high strength with low weight.

AUP (carbon fiber product) is hydrocarbon based. It has high strength, but due to its high cost, this type is not in wide demand.

ACC (combined product) made on the basis of basalt and fiberglass. It has high wear resistance and a wide range of applications.

Advantages of composite reinforcement

Composite reinforcement has rapidly gained popularity in the construction market. This is due to its technical performance and durability. Among the advantageous qualities:

- does not corrode;

— moisture resistance;

— long operational period;

— strength indicators exceeding metal analogues;

— low thermal conductivity, eliminating the formation of cold bridges in the concrete structure;

- affordable price.

Scope of application of composite reinforcement

The material is actively used in various construction works:

When laying the foundation of buildings, especially those that are operated in an aggressive environment;

In strengthening structures of foundations and load-bearing walls;

In private construction;

For road reinforcement;

To strengthen embankment slopes;

For the manufacture of connecting structures during the construction of buildings;

To strengthen the soil in mines, etc.

Features of structural reinforcement with composite reinforcement

There are no difficulties when reinforcing a structure with composite material. Masters in the usual way calculate the diameter of the rods and the parameters of the cells, taking into account the load-bearing capacity of the structure. The frame is made using binding wire or electrical plastic clamps. To make wire connections you will need a special hook and a knitting machine. automatic type. The clamps are attached manually. It is also allowed to connect reinforcement elements with plastic clips. Use familiar welding machine impossible on a dielectric material.
