Abstracts: The demand of natural sand is quite high as there is an extensive use of concrete in the world of globalization era and this will lead to certain problems in construction field. India is one of the countries that are facing the same problems as other developing countries. Due to this situation, some developing countries are facing a shortage in the supply of natural sand. Due to shortage of natural sand in Mumbai many construction site used quarry dust in place of sand. This paper reports the experimental study undertaken to determine the optimum mix ratio and compressive strength of compressed concrete using quarry dust. Four types mix proportions of sand with quarry dust were practiced in the concrete mixes that 0%, 15%, 30% & 50% (cement: sand: quarry dust) with 0.55 w/c ratio. Two types of curing methods, air dry and covered by gunny sack, under controlled laboratory conditions were practiced during the entire study. The concrete block of 150x150x150 is used for casting purpose. Then this specimen is cured for 7 & 28 days. The cubes are air dry for 15 to 20 min before testing. Before testing the weight of cube measured accurately. The result was finally compared with one ARPN Journal
