Abstract Phosphate cement-based materials is a new cementitious material condensation hardening a acid-base reactions,with rapid condensation sclerosis,high early strength,high compressive strength and little dry shrinkage,good wear resistance and good frost resistance, etc.Its excellent performance enables it can replace the traditional cement-based repair materials and meet the requirements of cement concrete structure repair.It has become one of the research hotspots of rapid repair materials.In this paper,the research progress of MPC as rapid repair material in recent years is reviewed.The setting time,fluidity,strength development,bong performance of MPC with old concrete structure,volume stability and inf-luence factors are discussed respectively.On this basis,the problems of MPC as repair material are discussed and some suggestions are given.

Key words： magnesium-phosphate cement rapid repair hydration mechanism performance
