Thanks, impermeability of the concrete shell is not exposed to the environment and therefore its composition may be selected only on the basis of the strength required. On the prospect of concrete with fiberglass reinforcing evidence of Ysian Gosstroy BSSR, USSR State Construction Committee NIIZhB, MIIT, KHISI, Si6NIIE, Moscow selenergoproekta, Ministry of Transport Research Institute and other organizations, as well as international experience. Types of Fiberglass Reinforcement Reinforcement SNA is internal, external and combined. The internal non-metallic reinforcement. Apply in the case when the environment is aggressive to steel reinforcement and is not aggressive to concrete. With aggressive Protection is applied to concrete external reinforcement.

Internal reinforcement can be divided into discrete and dispersed. Discrete reinforcement is fiberglass rods certain diameter, which used instead of steel. Not yielding to steel for strength, fiberglass rods are considerably superior to them for corrosion resistance and are therefore used in designs where there is a danger of corrosion reinforcement. Reinforcing bars are often combined into flat or three-dimensional mesh cages. Bond fiberglass rods in the reinforcing cages, you can use plastic samozaschelkivayuschihsya capping or binding. disperse reinforcement is the introduction of the concrete mixture while stirring chopped fibers (fibers) that are distributed randomly in the concrete. Special measures can achieve directional arrangement of fibers.

Concrete reinforced with dispersed commonly referred to as fiber-reinforced concrete. Exterior fiberglass reinforcement. The basic concept of the external reinforcement is multi-functional external sheet reinforcement. It can perform simultaneously three functions: power, safety and function of the formwork during concreting. Because the fiberglass shell is impermeable to water and air, it protects the concrete from the effects of the environment, but because high-strength serves as a reinforcement, and more efficiently than the internal rod, as is farther from the neutral plane. External reinforcement is divided into continuous and discrete. Continuous running listovtm solid material, discrete separate strips or grids.
