2021-6-4 natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or
Read More2021-6-4 use of natural sand. Quarry dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine particles less than 6mm. Natural sand in many parts of the country is not graded properly and has excessive silt. On the other hand, quarry dust

Read More2018-10-3 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. Therefore the concurrent use of quarry dust
