· Quarry dust is used as partial sand replacement for sand namely as QDC5, QDC10, QDC15, QDC20 and QDC25 for 5%, 10%, 15%, 20% and 25% replacement respectively following normal concrete as OPC. All specimens were tested for compressive strength at the age of 7, 14 and 28 days. Based on the result, it shown the compressive strength of concrete increase due to increasing .

· Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are wellrounded and are usually nearly spherical. Spherical particles decrease the percentage of voids within the concrete mixture so no additional paste is required to fill these voids. Wellshaped natural sands are ideal for workability of mixtures. Natural sand does not require more water to ...
