Tuning the phase structure and mechanical performance of magnesium oxychloride cements by curing temperature and H2O/MgCl2 ratio

The curing temperature and H2O/MgCl2 mole ratio are the two main factors that affect the structure and mechanical performance of the magnesium oxychloride (MOC) cement. In this work, different curing temperatures and H2O/MgCl2 mole ratios were used to synthesize MOC cement. The structure of the MOC cement samples was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The mechanical performance of the samples was also evaluated.

养护温度与H₂O/MgCl₂摩尔比是影响氯氧镁（magnesium oxychloride, MOC）水泥结构与力学性能的两大核心因素。本研究设置不同养护温度与H₂O/MgCl₂摩尔比，合成了系列氯氧镁水泥试样。采用X射线衍射（X-ray diffraction, XRD）与扫描电子显微镜（scanning electron microscopy, SEM）对试样的结构进行了表征，并对试样的力学性能开展了评估。
