Abstract: The rapid rate of growth in population of India has forced the construction industry to use the building materials at a rapid rate, resulting in depletion of natural resources and also has a severe impact on the environment causing many hazards. Due to rapid growth and production, vast quantities of waste are generated in India. This thesis work is focused on making an effort to use copper slag which is an industrial by-product of Sterlite Industries Ltd (SIL), Tuticorin, Tamil Nadu, India. An experimental investigation was carried out to evaluate the effects of replacing fine aggregate by copper slag and steel fibre as an additive on mechanical properties of concrete. The whole study was done in two phases. In the first phase the feasibility of copper slag as fine aggregate was checked by preparing concrete mix of M30 grade and studying the effect of copper slag on mechanical properties of concrete. Optimum replacement percentage of copper slag was obtained as 40%. In the second phase, the properties of concrete with optimum copper slag content and various percentage of steel fibre was studied. The steel fibre reinforcement was varied from 0.50%-1.75% by weight of cement. The two types of steel fibres used are crimped fibre and hooked end fibre. The results showed that the compression strength is highest for 1% steel fibre addition for both hooked end and crimped fibre. The concrete containing the hooked end fibre shows more compressive, tensile and flexural strength compared to concrete containing crimped end fibre.
