氯氧镁水泥是由轻烧菱镁石粉和氯化镁水溶液按一定比例混合而成的一种新型镁质气硬性胶凝材料。它有很多优于普通硅酸盐水泥的性能,但其耐水性差等缺点也很突出。为了使氯氧镁水泥得到更好的应用,总结和分析了氯氧镁水泥的研究进展,包括水化行为、水化产物组成和结构、耐水性以及生产应用方面。指出了氯氧镁水泥在当前的发展过程中存在的不足和问题,以期为后续氯氧镁水泥的进一步研究提供参考。

Magnesium oxychloride cement is a new type of magnesia air hardening gelled material which is made of caustic calcined magnesite powder and magnesium chloride aqueous solution in a certain proportion.Many of its properties are better than that of ordinary Portland cement,but its poor water-resistance is quite obvious.In order to make better application of magnesium oxychloride cement,the research progress of magnesium oxychloride cement are summarized and analyzed,including hydration behaviors,hydration product composition and structure,water resis-tance and production application.It points out deficiencies and problems existing in the current development process of magnesium oxychloride cement,aim to provide a reference for the further study of the magnesium oxychloride cement in future research.
