This paper deals with the experiments conducted to study the effect of copper slag, GGBFS (Ground Granulated Blast Furnace Slag), metakaolin on the properties of concrete. While GGBFS and metakaolin are used as partial substitutes for cement, copper slag is used as a partial substitute for fine aggregate. This study investigates the mechanical strength of the concrete in terms of compressive strength, flexural strength, split tensile strength, bond strength and durability performance such as water absorption, porosity and sorptivity. In addition the effect of cement and fine aggregate substitution on the microstructure of concrete is also discussed. The results indicated improved strength properties with decreased cost consumption leading to greater efficiency and reduced river sand consumption as an additional benefit.
