Raman et al., 2005 studied the effect of quarry dust and found that the partial replacement of river sand with quarry dust without the inclusion of fly ash resulted in a reduction in the ...

This paper presents the feasibility of the usage of Quarry Rock Dust as forty percent substitutes for Natural Sand in concrete and cement is replaced by fly ash. Mix design …

The substitution of fly ash for cement potentially increased the alkaline and acid resistance and also improved the thermal performance. Also, the replacement of fly ash for cement in the masonry blocks significantly reduced the total cost, embodied energy and CO 2 emission. It can be inferred from the study that using quarry waste as a full ...

Geo-polymer concrete was mixed along with fly ash and quarry dust. geo-polymer concrete was placed in to the standard mould in layer and compacted. Demoulding was done after 24 hours of casting and the specimens were cured under ambient heat curing at 28 days. After 28 days of ambient curing, the specimens were taken and testing is done.

Further when fly ash is partially replaced with cement from 0 to 30% in mortar with 20% quarry dust (QF series), there is an overall increase in strength at 3 days, 7 days, and 28 days of age. The drop in compressive strength due to conversion reaction decreases with increase in fly ash content for a given water to powder ratio.
