The blocks comprised of different percentages of laterite soil (76%, 81%, 85% and 87%), quarry dust (9% and 10% by weight of the soil) and ordinary Portland cement (3%, 5%, 10% and 15% by weight of the soil. The results showed that cement content of 10% and 9% quarry dust was suitable for the block at any curing period above 7 days.

Quarry rock dust (QRD), a waste obtained during the quarrying process is a significant source of air pollution yet has the potential of becoming a sustainable and economical alternative to sand in concrete. Studies confirmed that replacing sand in conventional concrete with QRD increases its durability and robustness by ten percent.

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low …

The specific gravities for laterite, quarry dust and crushed cay bricks were found to be 2.392, 2.62 and 2.273 respectively. The workability of concrete using laterite, quarry dust and crushed clay bricks was found to have the same trend with normal concrete. Slump and compacting factor tests were used to measure workability.

The Dust contents higher than 15% increases the water absorption of the. concrete. Partial replacement of sand by stone dust in concrete also reduces workability but the. compressive strength and ...

The strength of hardened concrete using quarry dust and lateritic sand as full replacement to river sand was studied by casting different specimens like cube, cylinder and prism.
