matrix basalt reinforcing member constructed and arrange to provide lateral support for the longitudinal bar steel or frp tendons that provide tensile strength to cementitious material or plastics to reduce bending moment by reducing the onset of shear . the reinforcement members are formed from basalt fibers treated with a thermoplastic thermoset polymer and formed into structures to provide structural resistance to bending - moment forces , compression forces , and torsional forces acting on the structure .
