Abstract

In this study, M20 grade of concrete was produced by complete replacing fine aggregate by Iron ore tailings, and GGBS as partial substitute to cement at 10%, 20%, 30% and 40%. The cubes were casted and their compressive strengths were evaluated at 7, 14 and 28 days. As the percentage increased the strength is also increased but only up to 30% further the strength is decreased. Replacing fine aggregate with mining waste will decrease the cost of concrete and using mining waste for different purposes in construction field will be a good impact on the environment.
