Experiment on Improving Performance of Recycled Coarse Aggregate from Waste Concrete

Abstract:

Recently recycled coarse aggregate concrete tends to be developed by using waste concrete considering environmental issues and conserving natural resources. However, performances of recycled coarse aggregate concrete are relative low compared with ordinary concrete due to the differences between recycled coarse aggregates and natural ones. In this research, developed mill is used to shuck the cement paste adhering on the surface of coarse aggregates to obtain shucking recycled coarse aggregates. Experimental results demonstrate that the performances of shucking recycled aggregates and concerned concrete are both improved.
