Abstract
The main objective of this research is to investigate the possibility of utilizing waste steel slag in concrete production. After the formation of by-product steel slag, in large amount from steel industries. This steel slag is disposed to open land area, it makes land pollution and harmful to environment. It has good physical parameters and gives enough strength to concrete and due to this it is suitable to bear heavy load. In this study workability, density before and after curing of concrete and strength parameters are evaluated by replacing the coarse aggregate by steel slag in 20%, 40%, 60%, 80%, and 100% by weight for Water–Cement ratio 0.42 in M20 grade concrete mix. The percentage of replacement which have been studied were, and evaluated the effect on workability. This study shows better strength of slag coarse aggregate concrete than conventional concrete mix
