Effect of Selected Admixtures on the Properties of . - Science DirectAs shown in the absorption and capillary action tests, the gains in the mass of the samples decreased with the increasing amount of admixture in the form of mineral dust. The mineral dust used for laboratory testing was a waste material derived from an aggregate quarry. The dust is used to a small extent mostly for primers,.quarry dust with admixtures,Improved Concrete Properties Using Quarry Dust as Replacement .that Quarry dust improves the mechanical properties of concrete as well as elastic modulus. .
