[PDF] An Experimental Study on Usage of Quarry Rock
But, now-a-days river sand is at great rate of depletion and expansive, due to which there was a need for an effective alternative. Quarry dust, has been found as an economic alternative for sand. In this , we have investigated the study of quarry rock dust as partial replacement of fine aggregate in concrete.
