Properties of concrete made with recycled aggregate from

In such concrete the combination of strength and cementing capacity of the recycled aggregates crushed at 3 days provides better strength over crushing ages of 1 or 28 days In a weaker new cement matrix this effect is reversed and the new concrete made from recycled aggregates crushed at 3 days was slightly weaker than concrete made from
