Increasing maximum use of sustainable materials in construction has lead to use of a variety of aggregate replacement materials in concrete. The scarcity of natural gravel and crushed stone aggregates has made it to utilize alternative materials for use in cement concrete. There are good quantities of waste materials available like fly ash, concrete waste, silica fumes, marble scum, industrial waste, agricultural waste, red soils etc. Use of many of this waste has become common in producing various products like fly ash concrete, jute boards etc. One of such waste material is recycled aggregates produced throughout the world in the form of crushed construction and demolished waste. The goal of this study was to show that the use of recycle aggregate in concrete is technically feasible. In this paper there for an attempt has been made to use recycle aggregate to replace course aggregate and finding are given. This research there for deals with studying the performance of concrete by replacing natural aggregates with recycle aggregates.
