Reseach Development on Hydration Product,Phase Transformation and Water Resistance Evaluation Method of Magnesium Oxychloride Cement

The effective use of bischofite in the salt lake area in China for magnesium oxychloride cement(MOC) as a building material 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.
