Behavior of Cement Concrete Using Recycled Concrete Aggregates
The requirement of concrete aggregate in India is large. Corresponding to the current annual production of cement of 300 million tons, total requirement of coarse and fine aggregate for use in cement concrete, mortar and plasters of about 1500 metric tons per year is a safe estimate. There is difficulty in obtaining natural aggregates within economic distances. Search for alternate sources of aggregates thus assumes importance. One such alternative is recycled concrete aggregate derived from construction and demolition wastes, which allow conservation of natural resources and land.
