Performance of High Strength Basalt Fiber Reinforced Metakaolin Concrete

Abstract

The present work deals with the results of experimental investigations on high strength M60 basalt fiber
reinforced metakaolin concrete. Effect of these fibers on various strengths of concrete are studied. Fiber content
varied from 0.5 to 1.5% at an interval of 0.5 by weight of cement. Various strengths considered for investigation
are compressive strength, flexural strength, split tensile, and bond strength. Cube of size 100 mm for
compressive strength, beams of size 500 mm  100 mm  100 mm for flexural strength were cast. All the
specimens were water cured up 7 and 28 days and tested subsequently. The workability is measured with the
slump cone test. A comparison of results of high strength basalt fiber reinforced metakaolin concrete with that
of modified concrete showed the significant improvements in the results of various strengths.
