This project reports on an experimental program to investigate the effect of using copper slag as a replacement of fine aggregate on the strength properties. Copper slag is the waste material of matte smelting and refining of copper such that each ton of copper generates approximately 2.5 tons of copper slag. Copper slag is one of the materials that is considered as a waste which could have a promising future in construction Industry as partial or full substitute of fine aggregates. For this research work, M50 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0, 20%, 40%, 60%, 80% & 100% in concrete, to study the strength properties, compressive strength for curing periods of 7, 28, 56 & 90 days, Flexural strength and split tensile strength for curing periods of 7 & 28 days. The compressive strength of concrete cube increases up to 40% partial replacement of fine aggregate by weight. In the same, flexural & split tensile increases up to 40% replacement of fine aggregate by weight. The workability of concrete was tested and found good. The obtained results were compared with those of control concrete made with ordinary Portland cement and sand.
