Felekoglu et al. observed that the incorporation of quarry waste at the same cement content generally reduced the super plasticizer requirement and improved the 28 days' compressive strength of SCC. Normal strength SCC mixtures that contain approximately 300–310 Kg of cement per cubic meter can be successfully prepared by …
Five types of cement-sand-quarry dust wall plaster mortars were made. The volume ratios between sand and quarry dust were kept at 1:0, 4:1, 2:1, 3:2, and 0:1 while maintaining a constant cement amount for all mixtures. Then the strength and durability of plastering mortar were examined using destructive and non-destructive test methods. The
