Quarry dust as a by product from crushing process during quarrying activities is one of those materials that have recently gained attention to be used as concreting aggregates, especially as fine First category of the tests conducted to find the physical and chemical composition of the quarry sand.
The chemical composition of quarry dust and sand possess that the strength property remains constant for both the materials. The silica percentage is above 80 which gives the high strength as same as sand. It is observed that the difference of chemical composition for the quarry dust samples collected from various crushers.
