Stone Dust in Concrete: Effect on Compressive Strength

stone powder showed 14.76% higher value than that of the of normal sand (Mahzuz et al., 2011). It is found that the compressive and flexural strength of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete (Suribabu et al., ). In the present B.Investigation for the Optimum Replacement Level of FineEffectiveness of replacing cement partially with waste brick ,This investigation was aimed to find the optimum replacement level of waste brick powder (WBP) as a partial replacement of cement. For this purpose, three groups of tests are made: fresh, mechanical, and permeation properties. Eight mixes with different percentages of replacing ratios are as follows: 10, 15, 20, 25, 30, 35, 40, and 50%.Study on Compressive Strength of Quarry Dust as Fine,The partial replacement of quarry dust gave a 28 days’ peak compressive strength at 40% replacement level and decreases for 50% replacement. Figure 3 shows the compressive strength relation for both normal concrete and quarry dust concrete, at the age of 28 days for M30, M25, and M20 grades of concrete for different w/c ratios of 0.45 and
