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
Quarry Rock Dust: Quarry dust is fine rock particles. When boulders are broken into small pieces quarry dust is formed. It is grey in colour and it is like fine aggregate. The physical and chemical properties of quarry rock dust and the fine aggregate are listed in Table 1 and Table 2 respectively. Property of quarry dust and river sand
