2021-6-4 Another alternative is by using quarry waste to replace the 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 does not contain silt or organic impurities and can be produce to meet desired gradation and fineness as per requirement. Consequently, it improves the strength of concrete. Besides, waste can be used to produce new products or can be used as admixtures so that natural sources are used more efficiency and environment is protected from waste

Quarry dust as fine aggregate gives better result in compressive strength. The previous study also shows the optimum use of quarry dust with a better strength. The concept of replacement of natural fine aggregate (sand) by quarry dust may help in many ways rather than reducing construction cost. The Erosion of river bank might stopped

2018-10-3 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
