Description Quarry Dust can be used for asphalt, substitute for sand, and filling around pipes. It can be an economic alternative to the river sand. Usually, Quarry Dust is used in large scale in the highways as a surface finishing material and also used for manufacturing of hollow blocks and lightweight concrete prefabricated elements.


Dust Containing Silica A major health risk encountered by people working in the quarrying industry is exposure to fine respirable dust which contains silica. Silica is found in the majority of rocks, sands and clays and therefore workers within the quarrying industry and masonry industry are particularly susceptible.

Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.
