Abstract :

Global warming and environmental destruction have become the major issue in recent years. Use of more and more environmental friendly materials in any Industry in general and construction industry in particular, is of paramount importance. Preventing the depletion of natural resources and enhancing the usage of waste materials has become a challenge to the scientist and engineers. In this study fine aggregates of concrete are replaced by steel slag which is an industrial byproduct getting generated in large quantity and replacing lime stone as coarse aggregates. SS (Steel slag) is a waste by–product obtained from the iron and steel plants and waste limestone aggregates are the waste oken pieces of limestone obtained from the limestone quarries. In this work, we have made an attempt to study the compressive strength of M20 grade cement concrete by using steel slag and waste limestone aggregate as partial replacement to fine aggregates and coarse aggregates. The compressive strength test is evaluated for 3,7,21 and 28 days of curing period with various percentage variations of steel slag. The compressive strength of cement concrete is highest at 40% SS replacement, which is 31.186 N/mm2 at 28 days of curing period. which are higher than the normal conventional cement concrete strength. From this study it is concluded that the natural fine aggregates can be replaced by steel slag up to 50%.
