摘要
磷酸钾镁水泥是由重烧氧化镁和磷酸二氢钾通过酸碱反应生成的磷酸镁盐类胶凝材料,具有凝结硬化快、早期强度高、低p H环境、良好的生物相容性等特点。服役性能对磷酸钾镁水泥的应用推广具有重要影响,文中主要从磷酸钾镁水泥耐水性能、体积稳定性、耐化学侵蚀及其微观结构发展等方面对磷酸钾镁水泥的服役性能进行总结与探讨,并给出了一些建议。
The Potassium magnesium phosphate cement is a magnesium phosphate cementitious material formed by acid-base reaction of calcined magnesium oxide and potassium dihydrogen phosphate.It has the characteristics of fast hardening,high early strength,low pH environment,and good biocompatibility.The service performance has an important impact on the application and popularization of potassium magnesium phosphate cement.In this paper,the service performance of potassium magnesium phosphate cement is summarized and discussed from the aspects of water resistance,volume stability,chemical corrosion resistance,and microstructure,in which some suggestions are given.
