Because of the increase in construction activity, the accessible sources of natural sand are becoming depleted as a result of the use of sand in construction. High-quality sand can be transported over long distances, causing economic hardship. As a result, the quality of the structure is completely reliant on the partial or complete replacement of alternate material with natural sand. The effect of quarry dust on the mechanical properties of concrete has been experimentally studied and reported in this research work. The concrete was made by partially replacing sand content 20% and 30% by weight with quarry dust. In first stage, concrete with no sand replacement of grade M25 is prepared so as to compare with the other trial cases of concrete having partial quarry dust. Cube and prism specimens were prepared for the two replacement levels of 20% and 30% to obtain the compressive strength, flexural strength at 28 days. Total no of 18 specimens were made for this research work. From the results, it was observed that the flexural strength of concrete with 20% and 30% quarry dust were higher compared with concrete with no quarry dust. It was found that incorporating quarry dust in concrete improves its flexural strength.
