Abstract: The study presents the evaluation of steel slag in concrete compared to natural aggregate in concrete. Steel slag is obtained glass like product left over after the desired material has been smelted from its raw ore. It is the mixture of metal oxides and silicon di-oxides. Steel slag was selected due its characteristics which are almost similar to conventional aggregates. There are many grades of steel that can be produced, and the properties of the steel slag can change significantly with each grade. Grades of steel can be classified as high, medium, and low, depending on the carbon content of the steel. The compressive strength results obtained for specimen with steel slag was almost same as that of normal concrete specimen. Since the Steel slag is the by-product of steel industries, thus it is easily available and cheap. The main purpose of using steel slag was to save the natural aggregate and hence using the so called waste product and recycling it instead of dumping it in the environment. The study done is on M40 grade concrete with 25%, 50%, 75% and 100% replacement of conventional aggregates with steel slag and the maximum compressive strength is achieved.
