Although there is a critical shortage of virgin aggregate, the availability of demolished concrete for use as recycled concrete aggregate (RCA) is increasing. Using the waste concrete as RCA conserves virgin aggregate, reduces the impact on landfills, decreases energy consumption and can provide cost savings. Recycled aggregates are the materials for the future. The application of recycled aggregate has been started in many Western countries & Asian countries for construction projects. Research Paper reports the basic properties of recycled coarse aggregate. It also compares these properties with natural aggregates. Basic changes in all aggregate properties were determined. Basic concrete properties like compressive strength, flexural strength, workability etc are explained here for different combinations of recycled course aggregate with natural aggregate. In gen- eral, present status & utilization of recycled coarse aggregate in India with their future need is discussed.
