POLYMER BASALT FIBER COMPOSITES IN CONSTRUCTION
The features of the use of basalt fiber in the form of polymer composites for reinforcing concrete are considered. Basalt fiber is characterized by a number of advantages in comparison with polymer, glass or carbon fibers. Due to its natural origin, even after heat treatment, this mineral fiber is an environmentally friendly filler for polymers. The production of polymer composites from basalt-fiber materials makes it possible to obtain radio-transparent, seismic-resistant concrete products that are explosion- and fire-proof, including complex structures and objects. Modification of the surface of basalt fiber can be carried out by chemical and physical methods. The result of the modification is the formation of chemical bonds between the phases in the composite and an increase in the degree of adhesion with the polymer matrix. The stages of production of composite reinforcement for concrete from basalt roving are considered.
