Abstract
The experimental behaviour of M20 concrete in which the fine aggregate is partially replaced by Copper Slag is studied. Replacing fine aggregate with copper slag makes the concrete cost effective and imparts high strength. The amount of carbon dioxide (CO2) released into the environment during the production of Portland cement can be reduced. Copper slag is one of the materials that is considered as a waste material which could have a promising future in construction industry as partial substitute of either cement or aggregates. M20 grade concrete was used and the tests were conducted for various proportions of copper slag replacement with sand of 0%, 20%, 40%, and 60%, cement of 0%, 5%, 15% and 20% and combination of both (60% sand + 40% copper slag for fine aggregate and 85% cement+15% copper slag for cement) in concrete. The obtained results were compared with those of control concrete made with ordinary Portland cement and sand.
