摘　　要：磷酸镁水泥(MPC)是一种早期强度高、体积稳定性好、粘结强度高的新型胶凝材料,在工程快速修补、加固、国防建设等方面有重要价值,但也存在反应速度过快、凝结硬化时间短、成本高等问题,限制了MPC的应用推广。根据目前的研究,矿物掺合料可用于MPC改性,为使MPC在实际工程中更好发挥优势,文中从粉煤灰、矿渣、硅灰、纤维对MPC的改性效果进行总结,为MPC在重点工程中的应用提供参考。Magnesium phosphate cement(MPC)is a new type of cementitious material with high early strength,good volume stability,and high bonding strength,which has important value in rapid repair,reinforcement,and national defense construction fields.The application and promotion of MPC are limited by fast reaction speed,short setting and hardening time,and high cost.According to the current research,mineral admixtures can be used to modify MPC.In order to utilize the advantages of MPC in practical projects,this paper summarizes the modification effectiveness of fly ash,slag,silica fume,and fiber on MPC,providing reference for the application of MPC in key projects.
