suitability of using quarry dust in concrete and to compare its properties with that of the conventional concrete. Hence a simple mix design procedure has been developed especially for M60 grade concrete. In this work, the feasibility of the usage of quarry dust as 60:40 proportion of substitution of natural sand i.e (quarry dust replaces 60% of natural sand) in concrete. Silica fume is added,Analysis of Concrete Made from Quarry Dust,concrete. Quarry dust is a byproduct that is generated from the crushing plants and which is abundantly available to an extent of millions of tons per year associated with disposal problems and serious environmental effects. [1] Mineral aggregate production produces a major amount of environmental waste within the form of fine material (quarry dust powder) this is especially a concern for the,USE OF QUARRY DUST IN CONCRETE AS REPLACEMENT FOR,Use of quarry dust in concrete help in workability of concrete. 6. Quarry dust is a waste product from stone crushing industry and available almost free-of-cost, as partial replacement for river sand.

I. INTRODUCTION oncrete is the most widely used composite material today. The constituents of concrete are coarse aggregate, fine aggregate, binding material and water. Rapid increase in construction activities leads to acute shortage of conventional construction materials. It is conventional that sand is being used as fine,The Hazards of Dust from a Pit/Quarry Operation,,Dust is also produced during overburden removal and construction of berms and from wind blowing over stock piles and across barren pit floors. Dust increases corrosion and is harmful to vegetation. “Fine particulate matter, 10 microns or less in diameter (PM 10) can be inhaled and is considered toxic. Smaller respirable particulate matter, (PM 2.5) with a diameter of 2.5 microns or less, is even more dangerous,
