The strength of recycled concrete is unstable, and its performance still needs further study. The combination of fixed sand and stone volume method and free water cement ratio method is used to determine the mix ratio of self-compacting recycled concrete. 24 sets of slump expansion tests and 24 sets of cube axial compression tests were carried out to study the effect of recycled aggregate replacement rate on the flow performance and axial compressive strength of self-compacting recycled concrete, and the performance conversion formula of self-compacting recycled concrete was given. The results show that with the increase of the regenerated coarse aggregate substitution rate, the fluidity and filling property of the self-compacting regenerated concrete mix decreased. The failure of self-compacting recycled concrete is mainly due to the failure of strength between old mortar and new mixture. As the substitution rate increases from 0 to 100%, the axial compressive strength decreases by 15.2%.
