Abstract
Recycled fine concrete aggregate can not be directly used for concrete for its large water absorption, so we get recycled concrete powder through grinding process, and carried out series experimental studies on the recycled concrete powder. The results show that the technical parameters of recycled concrete powder can achieve the requirements of S95 grade slag powder. The slump constant of recycled concrete mixed with recycled concrete powder is slightly less than slag concrete, while cohesiveness and water retention is better than slag concrete. Replace slag powder with recycled concrete powder, the recycled concrete has high early strength but post-intensity does not change significantly. The conclusion shows that recycled concrete powder can completely replace slag powder in concrete to realize full efficiency reuse of waste concrete.
