Comparison between strength of concrete by using M sand and copper slag

Abstract

The paper reports the effect of concrete using copper slag and M-sand as fine aggregate replacement. In this project work, the concrete grade M60 was selected and IS method was used for mix design. The properties of materials for cement, fine aggregate, coarse aggregate, copper slag and M-sand were studied for mix design. The various strength of concrete like compressive , split tensile , flexural were studied for various replacement of fine aggregate using copper slag and M-sand that are 0%,10%,20%,30%,40%,50% and 60%. The maximum compressive strength of concrete attained at 40% replacement of fine aggregate at 7, 14 and 28 days. The split tensile strength and the flexural strength were also obtained higher strength at 40% of replacement level at 28 days.
