摘　　要：在文献[3]研究的基础上,首次提出利用改变氯镁水泥水化产物的结晶形态从而大大改善氯镁水泥抗水性能的途径,并为实验所证实。本文报导了通过掺入添加剂使凝胶态结晶成为氯镁水泥水化产物的主要结晶存在形态的研究结果,并阐述了它们对氯镁水泥抗水性能的影响。还对硅酸盐水泥水化产物中的凝胶相与氯镁水泥中的凝胶态结晶的差异进行了讨论。Based on the study of(3),we first suggest that the change of crystalline mor-phology of hydrate products in hardened magnesium oxychloride cement can causethe improvement of water resistance of magnesium oxychlcride cement,which hasbeen confirmed by experiments.The present investigation reports the results that thegel-like crystalline morphology becomes the main morphology in hardenedmagnesium oxychloride cement by doping additives and relates these results to waterresistance of magnesium oxychloride cement.The differences between the gel phaseof hydrate products in portland cement and gel-like crystalline morphology in ma-gnesium oxychloride cement are also discussed.
