Experimental Investigation on Basalt Fiber Reinforced Concrete

Abstract

this thesis focus on experimental investigation on fiber reinforced concrete, works were carried out on experimental investigation of basalt fiber concrete. Properties of concrete were checked by testing cubes, cylinders and prisms. The specimens were cast usingM20 Grade concrete with locally available materials. The object of the present work is to study the effect of different proportions of fibers in the concrete and find out optimum percentage of fibers with maximum strength criteria. The specimens like cubes, split tensile strength and flexural strength. Concrete specimens with different proportions (0.25%, 0.30%, and 0.35%) of basalt fibers were cast along with control specimens. Based on the literature study, it was found that the basalt fiber concrete have better toughness and impact strengths than the control concrete. It was also found that the addition of basalt fiber in concrete changes the mode of failure from brittle mode of failure to ductile mode of failure when subjected to compression, bending and impact. Because of its high tensile property it improves tensile strength of concrete when mixed in optimum fiber ratio and has shown adequate enhancement in flexural behaviour such as Load-deflection, Moment-curvature and crack pattern.
