In such a situation the Quarry rock dust can be an economic alternative to the river sand. Quarry Rock Dust can be defined as residue, tailing or other non-voluble waste …
Quarry rock dust (QRD), a waste obtained during the quarrying process is a significant source of air pollution yet has the potential of becoming a sustainable and economical alternative to sand in concrete. Studies confirmed that replacing sand in conventional …
ABSTRACT. Concrete is a mixture of fine aggregate (sand), coarse aggregate (rock), cement, and water. The increasing demand of concrete for construction and development of infrastructure has drawn the attention of many researchers in searching for less expensive alternatives to the traditional materials employed in the construction industries in an attempt to reduce the high …

the target compressive strength by 12%. Both river sand concrete and quarry dust concrete for the selected water/cement ratio and mix ratio are suitable for non-structural applications and lightly-loaded members where high strength is not a prerequisite. Key words: density, compressive strength, concrete, river sand, quarry dust 1 Introduction
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 ratio of 30%, 40% and 50% was found to enhance the compressive properties.
The compressive strength test both conventional and replacement materials added concrete was performed on standard compression testing machine of 3000kN capacity, as per IS: 516- SLUMP CONE TEST: The measured slump values of quarry dust with constant water/cement ratio i.e. w/c ratio (0.5) are 65, 66,71,80mm for different mixes such as M1 (10% ...
