中文摘要：

在盐湖地区发展氯氧镁水泥（MOC）建筑材料是充分利用盐湖镁资源的有效途径之一。但MOC用作建筑承重材料,需进一步提高其长期抗水性。MOC科技工作者热衷于寻找各种抗水外加剂和抗水改性方法,而对于和抗水性密切相关的基础理论未有系统的研究报道、总结和分析。本文综述了有关MOC中水化产物的晶体结构和微观形貌的研究进展,分析了水化产物的相平衡及转变规律,介绍了评价MOC抗水性的方法。针对目前MOC基础研究过程中存在的问题,提出了未来的研究方向。

英文摘要：

The effective use of bischofite in the salt lake area in China for magnesium oxychloride cement （MOC） as a building mate- rial is concerned. The MOC material should be improved for the long-term water resistance. However, there is no any systematic study on this aspect so far. This review paper summarized and evaluated recent studies on the crystal structure and morphology, phase equilibrium, phase transformation of hydration product in MOC and the methods of water resistance assessment. In addition, future possible research studies on this aspect were also proposed.
