Abstract: This experimental work reports on the mechanical strength properties of three grades of concrete – Ordinary (M20), Standard (M40) and High strength (M60) concrete using scrap steel slag as coarse aggregate. No conventional gravel was used in making of concrete. Scrap steel slag is analyzed for its suitability to be used as coarse aggregate in concrete by evaluating its physical, chemical and durability performance. Detailed report on the material characterization of scrap steel slag is presented. The concrete was tested for its compressive strength, flexural strength and tensile strength at 28 days. Experimental work reports that scrap steel slag excels in mechanical performance in all there grades of concrete, except for that, the crushing value of scrap steel slag is higher than that of IS code’s specification for wearing surfaces. Hence it is observed that the scrap steel slag is suitable to be used as coarse aggregate in concrete other than wearing surfaces.
