Behavior of Quarry Rock Dust, Fly Ash and Slag Based …

Cohen et al. (2019) studied the integration of dolomite-based quarry dust waste material as a partial replacement of cement and FA in cement-based (CEM) and FA-based geopolymer mortars, respectively [9]. The FA was replaced by quarry dust wastes at five different percentages, i.e., 0%, 10%, 20%, 30%, and 40% by weight of total geopolymeric binder.

Use of Quarry Dust as fine aggregates by Partial …

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. ...

Quarry dust

The flexural strength of concrete was reported to increase by 14 and 21% when quarry dust and waste foundry sand were used at the mass proportion of 70:30 and 80:20, respectively. The quarry dust and waste foundry sand's mass proportion of 80:20 had been defined as the optimal combination ratio for best flexural strength performance.
