Abstract: Self compacting concrete is the latest development in the concrete technology for better durability, high deformability and fluidity for construction industries. In this paper, mechanical properties of self-compacting concrete (SCC) made with iron slag (IS) are investigated. The possibility of using it as partial replacement of fine aggregates in concrete mix is studied and evaluated based upon the percentage of the partial replacement of fine aggregate with iron slag. In this research work, iron slag obtained from industry is replaced with fine aggregate accordingly in the reach of 0, 0.1, 0.2, & 0.3 by weight of M25 grade of concrete. Various tests were done for fresh SCC properties, compressive strength and split tensile strength. The experimental results showed that the iron slag replacement with fine aggregate content gives better strength than control mixture of self compacting concrete and can be suitably used in self compacting concrete.
