Experimental Investigation on Replacement of Sand by Graded Quarry Dust in Concrete

Abstract: Now a days the utilization and consumption of natural aggregates and cement as largest concrete component is rapidly and constantly increasing in the production of concrete. The developing countries like India, the infrastructure such as express highways, power projects, industrial structures, ports and harbors to meet the requirements of globalization in construction of buildings and other structures. River sand is one of the constituent used in the production of concrete, become expensive and also a scarce material. In view of this, there is a need to identify suitable alternative material from industrial waste in place of river sand. The utilization of quarry dust which is a waste material has been accepted as building material in many countries for the past three decades. Recycling involves processing used materials into new products in order to prevent the waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air and water pollution by reducing the need for conventional waste disposal. Concrete traditionally consists of cement, fine aggregate, coarse aggregate and water. An attempt has been made to replace the fine aggregate with quarry dust with an objective of utilizing the waste material.
