Steel slag, one of the by-products obtained from manufacturing of iron and steel which can be used as partial replacement for fine aggregate in concrete thus by reducing the quantity of river sand. Compression test, split tensile test, flexural strength tests were carried out with 0 to 50% proportions of steel slag as replacement of fine aggregate.
The utilization of steel slag for industrial and construction purposes has gained significant attention in recent years due to its abundant availability and potential environmental benefits. This study explores the feasibility of utilizing steel slag as a coarse aggregate in concrete, aiming to determine the optimal replacement percentages for …
