The project is about replacing sand in concrete production with quarry dust at varying percentage (0%, 25%, 50%, 75% and 100%) to check if the strength matches that of grade MIS with a mix ratio of I :2:4 and also the proportion which has the highest strength. The test carried out includes particle size analysis, slump test, and compressive test.

Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be replaced to the amount 25%. Its Availability is not a concern.
