Experimental Study on Granite Powder as a Replacement of Fine Aggregate in Concrete

CIVIL ENGINEERING

Throughout the world as a result of growth in infrastructural development and consequent increase in consumption has led to a fast decline in available natural resources. In contrast the ornamental granite production has produced enormous amount of by-product in the form of fine particles as a result all the construction and environmental industry concerned about the disposal of those million tons of fine materials. The main objective of this study is to experimentally investigate the suitability of granite powder by-product as a substituent material for fine/natural aggregate in concrete production. This paper presents the physical and chemical characterization of the GP by-product as well. The experimental parameters were grade of concrete and percentage of granite powder substition. The cubes are prepared by 0%,10%,15%,20% of fine/natural aggregate substation GP by-product on behaviur of concrete, compressive strength on cubes are perform. Experimental results revealed that compressive strength and axial stress strain behaviour of the substition rate upto 20% is fairly greater than values obtained with natural aggregates and it is suggested that substition of natural aggregates by GP by-product upto 20% is favourable for the concrete resistance.
