Properties of concrete made with recycled coarse aggregate ...

2013-11-5  Demolition of old buildings has produced a large amount of waste material. In this paper, experiments were performed to design the mix proportion of concrete made with recycled coarse aggregate from waste brick, and the workability, mechanical performance, and durability of the concrete with different contents of recycled coarse aggregate have also been investigated.

2003-5-1  The properties of recycled WPC concrete made with recycled aggregate crushed at age 3 days were significantly better than those of concretes made with aggregate crushed at age 1 or 28 days. Opposing trends were seen in recycled OPC concrete in which the new cement matrix was weaker than that of the WPC concrete at the same water to cement ratio.
