4 Dean of the department, Department of civil engineering, SNS College of technology, Coimbatore-35,Tamil nadu, India, Abstract - Major initiatives are taken by developing countries like India in developing 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. Concrete plays a major role in the construction industry and a large quantum of concrete is being utilized. River sand, which is one of the constituent used in the production of conventional concrete, has 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 and to lower green house gas emission as compared to virgin production. Recycling is the key component of modern waste management system and is the third component of waste hierarchy, "Reduce, Reuse, and Recycle". 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. It is found that quarry dust improves the mechanical properties of concrete when used along with super plasticizers.
