Abstract: Self-compacting concrete has the characteristics of high fluidity, anti-segregation, and better compactness, which is beneficial for the improvement of engineering quality and the reduction of the project cost. The addition of recycled aggregate into self-compacting concrete realizes the recycling of construction and demolition waste. To ensure the feasibility and safety of self-compacting recycled concrete applied in practical engineering, a large number of the modified studies on the workability and mechanical properties of self-compacting recycled concrete must still be further carried out. Based on the rheological compaction mechanism of self-compacting concrete, the design principle of self-compacting concrete proportion was summarized. The research progress of workability and mechanical properties of self-compacting recycled concrete were further summarized and reviewed. Finally, the problems existing in the current research on the workability and mechanical properties of self-compacting recycled concrete were analyzed, and then the future development of self-compacting recycled concrete was prospected. This research will be helpful for promoting the large-scale application of self-compacting recycled concrete in the practical engineering.
