investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and

However, when the cost per unit compressive strength was considered, quarry dust as river sand replacement seemed more beneficial, especially for mortar mix substituted with higher quarry dust. The reduction in cost per unit compressive strength was 9.2% for 33.3%, 23.2% for 66.6%, and 31.3% for 100% quarry dust substitutions, respectively.
