A STUDY ON RECYCLED CONCRETE AGGREGATES

The recycled aggregate concrete is made by mixing 60% of recycled aggregates with 40% of crushed stone chips. The aggregates used for concrete batching are maintained at saturated surface dry condition. The workability of the recycled aggregate concrete is slightly lower than that of the conventional concrete.
