Use Of Quarry Dust In Concrete As
construction work. quarry dust is produced from crusher unit and each crusher unit is produced nearly 22% to 27% of dust. this dust is completely waste material for crusher unit but quarry dust is useful for construction work as sand. If we mix quarry dust in sand then only 65% to 75% of sand replaced by quarry dust because strength of concrete iskeywords: quarry dust, sand, concrete, compressive strength. introduction:- quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated concluded that the compressive strength of concrete, with 50% sand and 50% quarry dust under thermo shock and high temperature showed the least reduction in strength. It was finally concluded that quarry dust can be effectively used for 50% replacement of sand in the conventional concrete. utilization of quarry dust as fine aggregates is higher than the conventional concrete. the durability of quarry rock dust concrete under sulphate and acid action is higher than the conventional concret. similarly water absorption found to be more in the concrete containing crusher dus. the overall workability value of quarry rock dust concrete in terms of slump as well as
