Abstract

In plain cement concrete the tensile properties is to be improved. The addition of steel fibres improves the resistance of conventionally reinforced concrete members towards cracking, deflection and other serviceability conditions. In addition, the replacement of coarse aggregates with coconut shell is one of the economical enhance Programme. Compressive strength for both conventional and coconut shell concrete targeted to M25 grade. The cubes were cast and tested for compressive strength to find the optimization of percentage of steel fiber. In this study steel fibers are added from 0.5 % to 2.0 % by volume fraction. From the test results, the optimized percentage of steel fiber for both conventional concrete and coconut shell concrete have been found as 1.0 % and 1.5 % respectively.
