Concrete is being widely used for the construction of most of buildings, bridges etc. Hence it has been properly labelled as the backbone to the infrastructure development of a nation. Cement, fine aggregate and coarse aggregate are the main ingredients of concrete. Investigations are carried out to explore the possibility of using fly ash and copper slag as a partial replacement of cement and sand in concrete mixtures. The effects of replacing cement and fine aggregate by flash and copper slag on the compressive strength of cubes, spilt tensile strength of cylinders and flexural behaviour of beams are evaluated in this work. Six test groups are constituted with the replacement percentages of 0% (Control) 10%, 20%, 30%, 40% and 50% copper slag with sand in each series and 15% of cement replaced by fly ash except control specimen. The results showed the effect of fly ash and copper slag on concrete
cubes, cylinders and RCC beams has a considerable amount of increase in the compressive, spilt tensile strength and flexural behaviour characteristics.
