Replacement of recycled coarse aggregates with natural

The aggregate are placed as per volume in the cubes but the specific gravity of N.C.A. & R.C.A. are different. Thus we can’t replace recycled coarse aggregate (R.C.A.) directly with the same amount of natural coarse aggregate (N.C.A.). We know the fact that volume of both aggregates should be equal.A STUDY ON RECYCLED CONCRETE AGGREGATES,The properties of the recycled aggregate and of the new concrete made from it, with nearly 100% of aggregate replacement, were tested.
