In addition, quarry dust is utilised in the manufacturing of concrete cubes at a replacement level of 30% by fine aggregate. These cubes were allowed to cure for seven days, twenty-eight days, fifty-six days, and ninety days, and then the results of compressive strength and split tensile strength tests were recorded.

Therefore, need to use this. The quarry dust is use in the concrete and the properties are studied experimentally and presented in this paper. Concrete is prepared with the process of replacing sand which isnatural/of river by dust produced from quarry of rock with the percent proportions which varied from 0%, 25%, 50% and75%.
