摘 要:基于石膏和氯氧镁胶凝材料进行了复合改性研究,通过对试件硬化体微观晶体形貌的观测,分析了石膏-氯氧镁系复合气硬性胶凝材料改性的作用机理。结果表明,石膏-氯氧镁系复合气硬性材料在适宜的配比下可以制作凝结时间适宜、耐水性好、强度高以及干燥收缩率低的新型胶凝材料。
Abstract: Based on the compound modification research on the cementitious material of gypsum and magnesium chloride, by the observation of the microstructure of the hardened specimens, the modification mechanism of the gypsum magnesium chloride composite air hardening cementitious materials was analyzed. The results showed that, a new gel material with appropriate setting time, good water resistance, high strength and low drying shrinkage can be produced by the air hardening composites when a proper ratio of gypsum to magnesium oxychloride is prepared.
