addition of quarry dust in concrete

Partial Replacement of Sand with Quarry Dust in Concretegives many benefits, such inclusion causes a significant reduction in early strength due to the relatively slow hydration of fly ash. Nevertheless, fly ash causes an increase in workability of concrete [2]. Quarry dust has been proposed as an alternative to river sand that gives additional benefit to concrete. Quarry dust is.addition of quarry dust in concrete,Partial Replacement of Sand by Quarry Dust in Concreteconcrete. This paper reports the experimental study which investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate.
