Abstract : In Indi, natural sand is used for concrete and masonry works such as plastering, boundary walls and block work. However growing demand for natural sand has led to depletion of reserves, exploitation of sand from river beds, jacking up of prices for sand. This paper evaluates the use of copper slag and granulated blast-furnace slag as an alternative to fine aggregate. Four copper slag mixes with different replacement levels of copper slag were evaluated. Effect on various properties of concrete of M 30 grades with replacement of 25%, 50% and 100% of copper slag were evaluated. For GBFS, the effect on workability and compressive strength of M 30 grade of concrete used in commercial ready mix concrete (RMC) with replacement level of 50% of fine aggregate with GBFS were evaluated. It was observed in both the cases that a replacement level of 50% is achievable in terms of meeting various criteria of workability and strength.
