| Abstract: | By means of DTA, XRD,SEM and corresponding means for measuring physical properties,the hydration mechanism of the magnesium oxychloride cement (MOC) prepared by calcined caustic dolomite was studied. Experimental results show that defects exist in the crystals of MgO and CaCO 3 in caustic dolomite,resulting in higher reactivity. A view of inert filler of CaCO 3 in caustic dolomite is rejected. The hydration mechanism and microstructure of the MOC prepared by caustic dolomite is similar to that of MOC by calcined magnesite. |
