Phase change concrete(PCC)is a new type of building material that absorbs or releases a large a-mount of heat over the phase change temperature range,demonstrating excellent performance in terms of ener-gy conservation and environmental protection.In this paper,the basic principle of phase change concrete and its development and application are summarized.Secondly,the research status of material properties,mechanical properties and thermal properties of PCM is analyzed,and the existing problems and challenges in the current research are pointed out.Finally,the experimental research and engineering application of PCM are summa-rized,and the intelligent development suggestions based on PCM composites are put forward.
