Cost Benefits Of Recycled Concrete And Other Waste Aggregate

The addition of foundry sand (fine material) to aggregate decreased resilient modulus values relative to that of aggregates. ìThese results suggest that the stiffness of RAP, RCM, and fly ash mixtures of aggregates will be similar or better than of aggregates,î they write.
