Abstract

Concrete is widely used material with an increasing rate due to its particular characteristics in construction field. This study was conducted to investigate the properties of concrete fine aggregate partially replaced with copper slag and a comparative study on strength properties was done with Rebound Hammer method and traditional compression testing method.Fine aggregate was replaced with copperslag in 10%,15%and 20% for M40 grade concrete.The strength values are evaluated for compression,split tensile and flexural strength.It was found at 20% replacement of fine aggregate with copper slag given maximum strength .The strength increment was 15.25%compared to nominal mix.
