50% quarry dust From figure 2 we can find out that 60% is the optimum replacement of cement with GGBS in both natural sand and quarry dust. Table 6 shows the split strength values for concrete with different percentages of GGBS with natural sand and 50% quarry dust. Table 6. split tenile strength of M20 concrete over

Practically the concrete made of crushed sand is more homogeneous as compared to natural (river)sand, because,aggregate and cement gets easily mixed having similar properties. Quarry dust is available at very low cost as compared to river sand. So cost of construction is also low and we too have scarcity of river sand.

Abstract Stone dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural river sand in concrete. Use of stone dust in concrete not only improve the quality of concrete but also conserve the natural river sand for future generations.

Usually, Quarry Rock Dust is used in large scale in the highways as a surface finishing material and also used for manufacturing of hollow blocks and lightweight concrete prefabricated Elements. Use of Quarry rock dust as a fine aggregate in concrete draws serious attention of researchers and investigators.

durability properties of concrete containing quarry dust as fine aggregate revealed that the overall workability value of quarry dust concrete is less, when compared to conventional concrete. Quarry dust concrete experiences better sulphate and acid resistance and its permeability is less, compared to that of conventional concrete.
