determine the optimum mix ratio of compressed concrete using quarry dust
EFFECT OF PARTIAL RE PLACEMENT OF SAND .
with quarry dust. Much work has been done on the partial replacement of sand with quarry dust in construction. These works focused primarily on concrete production [3, 6, 7, 8]. Works by [9] and [10] are among the few on the effect of partial replacement of sand with quarry dust in the production of sandcrete blocks. Again these works

Getting Good Concrete| Concrete Construction Magazine
Dec 21, 2011· Starting at the quarry. Good concrete depends on good aggregate. Coarse aggregate can be as much as 75% of the volume in a mix. The best stone for making concrete is hard, durable particles with moderate absorption. The worst aggregate used to make concrete is friable, weakly cemented sandstones with high absorption.

Mix Design of Cementitious Basecourse
However, the optimum moisture content corresponding to the tests show that the increasing cement content requires an increase in water content to achieve maximum compaction. This can be potentially explained with the conglomeration of fines which affects the void ratio of the mix and the absorption of cement during the reaction process.
