AN EXPERIMENTAL STUDY ON STRENGTH PROPERTIES OF CONCRETE BY PARTIAL REPLACEMENT OF CEMENT WITH MEATAKAOLIN AND FINE AGGREGATE WITH COPPER SLAG

Abstract

The strength of concrete using alternate materials is an important task of researchers. An Experimental work has been made to find the influence of Metakaolin (MK) as partial replacement of Cement and Copper Slag (CS) as partial replacement of fine aggregate on strength properties of concrete. Four concrete mixes were prepared using different proportions of Copper slag ranging from 0 to 100% and Metakaolin 0% to 20%.The effect of Metakaolin and Copper slag on Compressive strength, Split tensile Strength, Modulus of Elasticity and Flexural strength of M30 grade concrete were obtained. The addition of Copper Slag up to 50% as fine aggregate replacement and Metakaolin upto 15% as cement replacement attains strength of concrete comparable with that of the Control concrete. it is observed that at a combination of 15% of Metakaolin and 50% of Copper Slag is maximum strength.
