An experimental investigation on the use of quarry dust as a replacement material in concrete

Abstract

River sand the most commonly used fine aggregate in concrete is newlinevery expensive now Day by day the cost of sand is increasing due to the newlinescarcity and restrictions Huge quantity of sand excavated from river bed newlinedestroys the stability of river banks To avoid such situation and to meet the newlinedemand we have to think of an alternative or replacement material to sand newlineCrushed rock material fly ash and sea sand are some of the newlinealternatives Different sizes of metal like 40 mm 20mm and 10mm are newlineobtained by crushing boulders of rock into small pieces in crushers The newlineresidue of size less than 475 mm is called quarry dust which attracts various newlineresearchers as an alternative to river sand newline newline
