Due to a quick growth in population there have been many construction projects which are coming up. Projects like residential complexes help to accommodate the rising population, Commercial projects help in providing generating income employment and contribute to the economic growth of the country, Industrial projects are also experiencing a boom, Highway construction is also on the rise to facilitate quick transportation. Since, all the above mentioned construction projects are booming there is a rise need for construction materials like sand, cement, aggregates etc. Cement is obtained from manufacturing plants and is produced in bulk. Aggregates are obtained from quaries and mills. (Muralidharan. T, 2018) Sand is obtained by mining activities near river beds which have an adverse effect on the river beds. Hence, in this project an attempt is made to find a suitable replacement for sand to reduce mining activities near river beds. In this paper sand is replaced by Ceramic Tile Powder and Dolomite Powder in the proportions of 5%, 10%, 15%, 20%, 25%, 30% and 35% to minimize the amount of sand used and also to find the best suited proportion for which maximum strength improvement is achieved. Also, the slump of each sample has been tested in this paper.
