The properties of a new magnesium Oxychloride cement (MOC) material formed by silica fume uniformly mix in MOC paste was presents. The influence of silica fume on the water resistance and compressive strength of MOC paste was invesigated in this study. It is shown that when 30 weight percent of silica fume is added to the MOC paste, a high strength and water resisting new material with 112MPa compressive strength and 1 00 water resisting coefficient could by obtained.

The influences of solution cement ratio (Wn/C), MgO content of the magnesia, specific gravity of the MgCl 2 solutions and mixing regime on the rheological properties of magnesium oxychloride cement (MOC) pastes were studied with a rotating viscometer. It was found that different influential factors cause difference rheological properties of the MOC pastes.
