Basalt Fiber Rebar

Basalt Rebar is an outstanding product for concrete reinforcement. It weighs 4 times less than steel rebar and its tensile strength is 3 times higher. Basalt rebars are manufactured from basalt fibers by pultrusion technology. The surface is profiled and sanded. This kind of surface treatment results in a better adhesion in concrete.

Basalt Rebars are produced in diameters from 4 mm to 16 mm and the length of rebars ranges from 500 m to 800 m. The rebars are rolled up for transport. Due to the elasticity of rebars, they take their original shape when unrolling them. So, the rebars can be chopped to the desired lengths.

Basalt rebar is resistant to a corrosive environment. However, typical corrosion happens to the steel materials. Therefore at least 4 cm concrete layers are needed to keep the steel reinforcement safe. In case of basalt rebar concrete, this covering layer is reduced to 1 cm. This results in saving concrete and allows a lightweight construction.

With basalt rebars, the concrete reinforcement contains mainly a natural raw material which does not need a separation after the end of the lifecycle of reinforced concrete.
