Unique properties of composite reinforcement:

•Low density (4-5 times lower than steel one).

•Incombustible material.

•Chemical resistance.

•Non-corrosive material.

•Low heat conductor.

•Dielectric.

•Wide range of operation temperatures, UV resistance

Main characteristics of composite reinforcement:

•Corrosive resistance to alkaline environment of the concrete.

•I class chemical resistance (according to GOST 9.071-76. Unified system of corrosion and ageing protection. Vulcanized rubbers for articles working in liquid corrosive media) to saline, sea, ammonia water; sulphuric, chlorohydric and fluorhydric acids.

•Linearly-elastic “stress-strain” relationship

•Low thermal conductivity.

•Modulus of elasticity in tension and bending is not less than 40000MPa;

•Tensile and bending strength is not less than 1000 MPa;

•Operating temperature range is from -70°C up to +100°C.

Due to its strength characteristics, composite reinforcement in diameter 8 mm can replace metal rebar in diameter 12 mm.

Weight of 1 km of composite reinforcement in diameter 8 mm is only 65 kg vs. the weight of metal reinforcement is 400 kg. Tensile elongation is 5.6%.

Composite reinforcement is applied in light- and heavy-weight concrete (foam concrete, floor slab, roof slab, monolithic foundation), road construction (under asphalt coat) and as a flexible tie in three-layer walls of civil, industrial and agricultural buildings which include internal load-bearing layer, external finishing layer and insulation layer)

Today there are 2 types of construction ties:

•1st – to connect a load-bearing brick wall to a finishing brick layer.

•2nd – to connect a load-bearing monolithic wall to a finishing brick layer.

Application of composite reinforcement is not limited to civil, industrial and road construction. It can be expanded as long as experiment data are accumulated.

Composite reinforcement is three times lower in cost than metal one, it has higher strength and resistance, it returns to its initial position after the load is applied.
