USE OF QUARRY DUST IN CONCRETE AS REPLACEMENT

2018-10-3  Quarry dust is an alternate material of sand which is use in 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 is affected by this process. In other process if we mix quarry dust and fly ash are added together in concrete mix then we replace complete sand by quarry dust and fly ash. The use fly ash in concrete is desirable because of benefits such as useful disposal of by a by-product, increased workability, reduction of cement consumption, increased sulphate resistance, increased resistance to alkali – silica reaction decreased permeability.
