摘要：Now-a-days there is a rapid growth in the construction industry and it involves the use of natural resources for the development of the infrastructure. Therefore, to reduce the dependence on natural aggregates as the main source of aggregate in concrete, artificially manufactured aggregates and artificial aggregates generated from industrial wastes provide an alternative for the construction industry.In this study copper slag is used as a partial replacement to fine aggregates in concrete. Copper slag is one of the materials that are known as a waste material and which could have a bright future in construction industry as partial substitute of fine aggregates. It is a by-product obtained during the matte smelting and refining of copper. To manufacture every ton of copper, approximately 2.2–3.0 tons copper waste or slag is generated as a by-product material. The aim of the present work is to examine or explore the potentiality of replacing the fine aggregates by copper slag. An attempt is made to conform the effectiveness of copper slag as a partial replacement of fine aggregates. Because of the storing issues, the slag negatively affects the environment. To solve this trouble, fine aggregates was substituted up to 40% copper slag and determining its compressive and splitting tensile strength of concrete and also the performance of copper slag on strength properties as a partial replacement of fine aggregate in concrete mix design. The percentage replacement of sand by granulated copper slag were 10%,20%,30% and 40%. The compressive strength was observed toincrease by about 30-35%, flexural strength by 45-50% and split tensile strength by 40-45%.
