R. L. Shirale

Abstract

The present work deals with the results of experimental investigations on high strength M60 basalt fiberreinforced metakaolin concrete. Effect of these fibers on various strengths of concrete are studied. Fiber contentvaried from 0.5 to 1.5% at an interval of 0.5 by weight of cement. Various strengths considered for investigationare compressive strength, flexural strength, split tensile, and bond strength. Cube of size 100 mm forcompressive strength, beams of size 500 mm  100 mm  100 mm for flexural strength were cast. All thespecimens were water cured up 7 and 28 days and tested subsequently. The workability is measured with theslump cone test. A comparison of results of high strength basalt fiber reinforced metakaolin concrete with thatof modified concrete showed the significant improvements in the results of various strengths.Keywords: Metakaolin, basalt fiber, composites, HSBFRMC, fiber volume fraction, strengths
