Composite reinforcement is a new generation building material that has not yet become widespread. The performance of the product allows it to be used to replace the usual steel bars for reinforcing concrete products, building foundations, port structures, and in construction work on the roads.
Description and production process
The core part of the rods is made fiberglass, the coating is made of resistant to chemical influences polymer resins. Usually fiberglass reinforcement is produced in rods with a diameter of 0.5-3 cm, the surface of which can be coated sand spraying or have a spiral relief... Products with this texture have better adhesion to concrete than smooth ones.
First, the rods are impregnated with a polymer composition with curing additives and a reaction accelerator. The excess resin is squeezed out, after which the blanks are shaped. Then the polymer reinforcement is knitted with winding coiling (this is done to improve adhesion to concrete). The products are sent to the oven, where the shell finally solidifies. Then, segments of the required length are formed from them.
Specifications
Fiberglass reinforcement is characterized by low density (4 times less than that of steel) and, accordingly, light weight. This simplifies the installation process, reduces transport costs and the pressure of the erected structure on the ground.
