Abstract
Natural aggregates are becoming increasingly scarce, and their extraction and transportation are becoming more complex. There is a great opportunity to use steel slag, an industrial waste product produced as a by-product of steel manufacturing, as an alternative to normally available coarse aggregate. In this study, M25 grade concrete with w/c ratio of 0.4 is used for the partial replacement of 0%, 15%, 20% of the coarse aggregates with steel slag, which is a byproduct of the steel manufacturing industry and has a negative impact on the environment. This study revealed that there is an improvement in compressive strength upto 1 to 2%. The workability of concrete is reduced when % of replacement is increased to 15% and 20% when compare with normal conventional M25 grade of concrete. This suggests that there is an optimal replacement percentage of Steel slag that benefits the use of steel slag as coarse aggregate generally which increased the unit weight of concrete mixtures. Studies shows that a complete i.e., 100% replacement of coarse aggregate by steel slag reduces the strength of the concrete cubes
