摘要
磷酸镁水泥(MPC)是基于氧化镁与磷酸或水溶性酸式磷酸盐发生酸碱和水化反应的一种胶凝材料。MPC兼具传统水泥和陶瓷特性,在诸多领域具有广阔的应用前景。本工作分析近20年来MPC研究取得的主要进展,包括MPC的制备技术、水化硬化特性和机理、材料性能等方面;并介绍MPC在结构修补加固、防护涂层、有毒害和放射性废物固化、牙科和骨修复水泥等方向的应用情况;最后对MPC研究和应用所面临的问题进行讨论与展望。
Magnesium phosphate cement(MPC)is a kind of cementitious material,which involves both acid-base and hydration reactions between MgO and phosphoric acid or water-soluble acid phosphates.It has some application prospects in various fields due to its properties of both cement and ceramic.This paper analyzed the major advances in MPC for last two decades,including the preparation technologies,hydration and hardening mechanism,and material performance of MPC.The application of MPC for structure repair and strengthening,protective coatings,hazardous and radioactive waste immobilization,and dental and prosthetic cements was represented.In addition,some problems and applications of MPC were also discussed.
