The intention for taking up this research due to the fact that now a day's natural sand confirming to Indian Standards is becoming scarcer and costlier due to its non availability in time for the reason that of Law of Land, illegal dredging by sand mafia, ease of access to the river source during rainy season, non confirming with IS 383-1970. Therefore the present research was taken up with a view to authenticate the suitability, feasibility and prospective use of quarry dust, a waste produce from aggregate quarry plant in concrete mixes, in context of its compressive strength and workability and in terms of slump, compacting factor, flow table and modified flow correspondingly. Within view of above conversation, an attempt is made to substitute the natural sand in concrete control mixes of M20 and M30 grades designed for 25-50mm slump at replacement levels of 20%, 40%, 60% ,80% and 100% using normal portland zuari Cement. There were in all mixes in each grade of concrete together with control mix and five mixes with quarry dust as a partial replacement of natural sand. It was experimental that with use of quarry dust at all replacement levels, the workability of concrete was abridged from 1-6%. As of the test results, it was practical that the replacement of natural sand by quarry dust increased the compressive strength of concrete by 5-22%. It was also bring into being that in the middle of all the mixes, the uppermost compressive strength was obtained for 40% replacement of sand by quarry dust. Consequently it could be concluded and recommended that quarry dust could be successfully used in concrete of above grades for replacement levels of sand by 40-60% cost-effectively leading to sustainable development and improvement
