Application FRP-rebar in the Manufacture of Reinforced Concrete Structures

Abstract

Reinforced concrete is one of the first places in terms of use in various areas of construction. This is primarily determined by its relative cheapness and durability. Concrete Durability significantly associated with metal reinforcement durability. Durability depends upon the metal reinforcement corrosion that occurs under the influence of an aggressive environment. As a result, corrosion of the metallic reinforcement and, to some extent, of the concrete, there is a loss of bearing capacity of concrete structures in general and buildings. To ensure the durability of concrete structures is necessary to take measures against the development of concrete and reinforcement corrosion. The object of the study are reinforced concrete constructions basalt reinforcement. Restore the bearing capacity of reinforced concrete structures with corroded reinforcement is possible using known design techniques.However, essentially no use of technology in the construction field and specific data on the bearing capacity of concrete structures with basalt reinforcement. No complete information on the value of its adhesion to concrete and its dependence: the composition of concrete and its method of compression; treatment of the outer surface of basalt reinforcement in various ways to increase its adhesion to concrete; destruction of the nature of such structures from the effects of external loads.The search for alternative ways of replacement of the metal reinforcement in concrete structures bearing on the composite, not subject to corrosion and, at the same time having a high load-bearing capacity, is the actual research task. It is known that composite materials to minimize corrosion and other security and environmental impact. At the same time, they must be extremely reliable to manufacture environmentally friendly and does not emit harmful substances polluting the environment.Currently, intensive research to find ways to replace metal in structures of the other valves. An example of such research is to create different types of plastics, which are gradually replacing it. Work is underway in the field of replacement of the metal reinforcement in the non-metallic fittings on the basis of modern composite materials.A major breakthrough in this direction in recent years was the opening of “basaltic technology” that allowed the “update” the base of building materials for new building designs types of valves.
