An Experimental Study on Quarry Dust as Partial Replacement for Sand in Concrete

Abstract

Concrete plays the key role and a large  quantum of concrete is being utilized in every construction  practices. Quarry Dust which is a other non-voluble waste  material after the extraction and processing of rocks to form  fine particles less than 4.75mm.The Quarry dust can be an  alternative to the river sand since river sand is expensive  due to excessive cost of transportation from natural sources  and also large scale depletion of these sources creates  environmental problems .In this project work the usage of  different quarry dusts by studying the physical and  chemical properties, workability of the quarry dust  concrete, with different ratios of 0%, 20%, 30%&40% for  M20 grade of concrete behavior of quarry dust reinforced  cement concrete beams, Sieve analysis was conducted for  quarry dust and sand. Mix design has been developed using  IS Mix Design for various proportion of four different  quarry dust with river sand. Tests were conducted on cubes  and cylinders to study the compressive and tensile strengths  of concrete made of various proportion of quarry dust with  river sand, optimum strength test values of various  proportion of different quarry dust with river sand and the  results were compared with natural sand.
