Experimental studies on strength and behaviour of concrete by using quarry rock dust as fine aggregate

Abstract

Concrete as construction material has the largest production of all newlinematerials used in construction This is produced ten billion tonnes every year newlineand it stands next to the total consumption of water Conventionally concrete newlineis a mix of cement sand and coarse aggregate In our environment newlinetransportation and other constraints make the availability and use of natural newlinesand as fine aggregate less attractive So a substitute or replacement product newlinefor the concrete needs to be found newlineMost of the aggregate crushing plants in India adapt crusher newlineequipment by trade name JAW Cone VSI crusher incorporating rockon newlinerock crushing technology These crushing machines produce quarry rock dust newlineas a byproduct 1215 percent of crushed stone at every crushing plant newlineproduced newline newline
