purpose of producing coarse aggregates used for construction. The particles of quarry dust have diameters ranging from 0.05mm to 5.00mm. Agbode and Joel (2001) found in their study on the suitability of quarry dust as partial replacement for sand in hollow block production, that quarry dust is cheaper than river Benue sand
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.
You can buy stone dust at most stone yards and quarries. Some excavation companies also sell it, along with the crushed stone, sand, gravel, bricks, flagstones, etc. that you might need for other projects. For a fee, most of these places will deliver the product to your property. You may also be able to buy stone dust at your local Lowes or ...
If it is possible to use this quarry dust in making concrete by partial replacement of natural river sand, then this will not only save the cost of construction but at the same time it will …
