Abstract

The main scope of this research is to investigate the properties of concrete with steel slag coarse aggregates. The tests to be conducted are workability and strength of the concrete like compressive test, split tensile strength and flexural strength. Durability of concrete with steel slag coarse aggregate concrete is also to be included. The percentage replacement of coarse aggregate will be done in 25%, 50%, 75% and 100% by the steel slag aggregate. Thus replacing the natural coarse aggregate in concrete applications with steel slag would lead to considerable environmental benefits and would be economical. Steel slag aggregates generally exhibit the potential to expand due to the presence of un hydrated free lime and magnesium oxides which hydrate in humid environments. If such a product is used in the concrete, it influences both the mechanical and physical properties of concrete along with its durability. The purpose of this research is to explore the feasibility of utilizing the steel slag produced by steel industries as a replacement for natural coarse aggregate in the concrete. (Abdullah A.
