An influence of basalt fiber on mechanical properties of concrete

Abstract

The efficacy of fiber reinforced concrete in various application of civil engineering is unassailable. It is a heterogeneous material that includes the fibrous substance which increases its structural integrity and cohesion. In recent years, continuous basalt fibers extruded from naturally basalt rock are attracted attention due to its high temperature and abrasion resistance. Basalt fibers has emerged as a contender in fiber reinforcement composites. This paper aims to evaluate the outcome of basalt fiber on the mechanical strength of concrete and also identify the content that have a optimum influence on concrete. Compressive, split tensile and flexural strength of basalt fiber reinforced concrete is increased than the control concrete. The experimental study shows that the mechanical strength of concrete is increased up to 0.9% of basalt fiber in volume fraction. From the result it is observed that the optimum content of Basalt fiber is 0.9% and the ability of basalt fiber to arrest the cracks area indicated as reason for escalation in mechanical properties.
