6-6 EVALUATION OF BASALT FIBER PERFORMANCE FOR DISPERSED REINFORCEMENT OF CEMENT CONCRETE

Abstract

This study evaluates the feasibility of using basalt fiber as a dispersed reinforcing component in cement concrete. Basalt fibers produced by different manufacturers in Uzbekistan were compared in terms of production technology, raw material composition, geometric characteristics, and resistance to alkaline environments. Particular attention was paid to the behavior of basalt fiber in a cementitious alkaline medium. Experimental results showed that prolonged exposure to an alkaline environment leads to a gradual loss of fiber mass. The obtained results demonstrate that the chemical composition, geometric characteristics, production technology, and alkali resistance of basalt fiber should be considered when selecting reinforcing fibers for cement-based composites.
