Recycling Of Concrete Recycling Coarse Aggregate

It has been observed that the recycled coarse aggregate is used as normal aggregate. The workability of the concrete is increased by using RCA. Maximum properties of Recycled coarse aggregate have shown good with a little variation. Recycled aggregate materials produce harsh mixes with lower workability than Natural aggregates.
