To overcome from this crisis, partial replacement of sand with quarry dust can be an economic alternative. In this project determine the strength and durability of concrete by using quarry dust as sand and comparing with the conventional mix. Large range of curing period of 28 days are consider in the present study design mix of M20 grade concrete with replacement of 0%, 10%, 20%, and 30% quarry dust organized as M1, M2, M3, and M4 respectively have been consider for investigation. The compressive strength (cube) and split tensile (cylinder) strength of concrete were tested. The workability of concrete increases with various percentage replacement of quarry dust. Keywords: Sand, quarry dust (QD), sieve analysis, slum cone test,Compressive test 1. Introduction Concrete is the necessary construction Material in a building. The widely used composite material to prepare concrete is natural sand, coarse aggregate and binding material such as cement and water. Since we have many construction works all over the world and rapid increase in construction work and rapid increase in price of the construction material. we have a large demand in the natural resource of construction and material demand also. There is a large scarce for river sand all over the world as well as in India too. To solve this problem, to reduces the making cost of the concrete and to save the natural resource, we have to choose an alternate material for the concrete materials. So that we have choose some waste materials such as quarry dust. That is crushed powder from rocks which can be a replacement for fine aggregate. Which leads to a cost reduction for making of concrete. Which can be get easily from quarry waste, so that we can check the workability and strength of the concrete. If it satisfies the normal concrete quality and strength in we can use it as the replacement for the fine aggregate[1-4].Continues research efforts have established concrete as a versatile material, concrete required for extensive construction activity can be made available, since all the ingredients of concrete are of geological origin. Concrete is an assemblage of cement, aggregate and water. In the production of concrete, granite/basalt stone and river sand are used as course and fine aggregate, respectively although these materials are usually available, at some places it is economical to substitute these materials by locally available once. At the same time increasing quantity of crushed stone dust is available from crushers as waste. The disposal of this is a serious environmental problem. If it is possible to use this crushed stone dust in making concrete by partial replacement of natural river sand, then this will not only save the cost of construction but at the same time it will solve the problem of disposal of this dust. On the other hand, the advantages of utilization of byproducts or aggregates obtained as waste materials are pronounced in the aspects of reduction in environmental load & waste management cost, reduction of production cost as well as improving the quality of concrete. Quarry dust has been used for different activities in the construction industry such as road construction and manufacture of building materials such as light weight aggregates, bricks, and tiles. The use of quarry dust in concrete is desirable because of its benefits such as useful disposal of byproducts, reduction of river sand consumption as well as increasing the strength parameters and increasing the workability of concrete (Jain et. al., 1999). Attempts have been Concrete is an artificial conglomerate stone made essentially of Portland cement, water, fine and coarse aggregates. 2.
