Experimental study on steel fibre reinforced concrete with a partial replacement of cement by rice husk ash

Abstract

This present work is an attempt to made and investigate the split tensile strength, flexural strength and compressive strength of concrete by using crimped end steel fibre as an additive material and rice husk ash as a fractional replacement of cement due to its Pozzolanic reactivity. In this work we have kept the rice husk ash as constant and varied the steel fibre content as 0.5%, 1% & 1.5%. Mix design using IS code method is done and cubes, cylinders and beams are cast for M20 grade concrete. The concreting is done with and without addition of steel fibre and rice husk ash. Slump cone test is performed on fresh concrete. Cylinder test, Beam test are performed on concrete to study their usefulness and behaviour of additives and partial replacements. On comparing the test outcomes with the standard specimen test values where there is an appreciable improvement in tensile strength of concrete.
