Abstracts: As the infrastructural growth is at its peak in developing countries, large quantum of concrete is being utilized to cater the infrastructural requirement. Concrete plays a vital role in the construction industry and On the other hand River sand, one of the essential material used in the concrete, has become expensive and also a scarce material. The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes. In such a situation the Quarry rock dust can be an economic alternative to the river sand. Quarry Rock Dust can be defined as residue, tailing or other nonvoluble waste material after the extraction and processing of rocks to form fine particles. In this present work an attempt has been made to study various properties of quarry dust and its suitability in conventional concrete
