Experimental Study On Concrete by Partial Replacement of Aggregates

Natural aggregates are becoming increasingly scarce. The availability of natural sand and coarse aggregates is reducing drastically. In this investigation, fine and coarse aggregates are partially replaced with copper slag and ceramic tile waste respectively. Copper slag was replaced in proportions of 20%, 40% and 60% for fine aggregate and the tile waste are used in proportions of 10%, 30% and 50% respectively. Copper slag is the waste generated during the production of copper. The ceramic tile waste is nothing but the waste tile products from construction industry. M40 grade concrete was prepared for the experimental investigations, which showed that the ideal replacement for copper slag was 40% and that of tile waste was 30%.
