Review of studies on structural performance of recycled aggregate concrete in China

This paper presents a review of the studies on the structural performance of recycled aggregate concrete (RAC) elements and structures in the past 10 years in China. The flexural and shear behaviour of RAC beams, the compression performance of RAC columns as well as the flexural performance of RAC slabs are overviewed and summarized. The seismic responses of beam-column joints, shear walls as well as frames made of RAC are also covered. The experimental observations indicate that the structural performance of RAC elements and structures is somewhat similar to that of natural aggregate concrete (NAC) members. A brief introduction to the application of RAC in sustainable buildings in China is also presented.
