Quarry dust is a waste obtained during quarrying process. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand.

Adhering to the principle "reduce, reuse, and recycle," it has been found that the replacement of quarry dust for fine aggregates improves the mechanical properties of concrete. When the quarry dust is used along with super plasticizers, physical and chemical properties of the quarry dust satisfy the requirements of fine aggregate [ 10 ].
