Abstract : Concrete is the largely utilized construction material. The fine aggregates used in the production of concrete is twice the consumption of cement. But restriction on sand mining has created a need to replace the same by industrial byproducts which are threat to environment if disposed unscientifically. Slag sand is one such by-product obtained from smelting process in blast furnace of steel plants. Unscientific dumping and non-utilization of these creates serious environmental issues for dwellers living in the vicinity of steel plants. Hence, in this experimental investigation an attempt is made to find a secondary application to slag sand as fine aggregate by replacing river sand in the production of M25 grade concrete. River sand was replaced by 0%, 50%, 75% and 100% by slag sand designated as S0, S1, S2 and S3 in the preparation of concrete cubes of standard size 150 mm x 150 mm x 150 mm and prisms of standard size 100 mm x 100 mm x 500 mm were cast. Their mechanical properties such as compressive strength and flexural strength were tested. Fresh concrete was also tested for its workability. This study has revealed that slag sand is a promising alternative to river sand up to 75% replacement to river sand. Keywords - Concrete, Slag sand, River sand, Compressive strength, Workability
