COMPRESSIVE STRENGTH OF STEEL SLAG AGGREGATE AND ARTIFICIAL SAND IN CONCRETE

Steel slag is a byproduct of steel making processes of steel industry. It’s also one of the biggest industrial waste which is being produced worldwide in a huge quantity. This research deals with substantial replacement of natural aggregates and natural sand used in concrete. In this study coarse aggregate were partially replaced with steel slag aggregate with different replacement percentage in concrete i.e. 0%, 10%, 20%, and 30%. In which we found compressive strength of concrete with various percentage of steel slag aggregate. We found a significant increase in compressive strength at 20% aggregate replacement. We got an increase in compressive strength by 1.1 times than that of our convectional concrete.
