Experimental Study on Concrete Using Copper Slag as Replacement Material of Fine Aggregate

Abstract

This paper reports the effect of concrete using copper slag as fine aggregate replacementof fine aggregate. In this project work, M25 grade of concrete was taken for concrete mix design. The properties and characteristics of materials for cement, fine aggregate, coarse aggregate and copper slag was studied for concrete mix design. The compressive, split tensile and flexural strength of concrete were studied for various replacements of fine aggregate by using copper slag that are 0%, 20%, 40%, 60%, and 80%. At 40% replacement of fine aggregate, the concrete gains higher compressive strength, at 7 and 28 days. The maximum split tensile strength and the flexural strength were also obtained at 40% replacement level at 28 days.
