A parametric study has been conducted to investigate the influences of the molar ratios of MgO/MgCl2 and H2O/MgCl2 on the properties of magnesium oxychloride (MOC) cement. By an integrated assessment of the experimental studies of strength development and X-ray diffractograms, together with application of the relevant phase diagram, it is recognized that the molar ratios of MgO/MgCl2 and H2O/MgCl2 can significantly affect the properties of MOC cement. For a MOC cement paste possessing a dominanc...

Abstract This paper discusses the reasons why the addition of some soluble phosphates to magnesium oxychloride cement (MOC) can greatly improve its water resistance. With the XRD analysis and the determination of the strength retention coefficients (a judging index for the water resistance), it has been shown that the addition of small quantity of the soluble phosphates, such as H 3 PO 4 , NaH 2 PO 4 ·2H 2 O, and NH 4 H 2 PO 4 , to MOC pastes does not influence the phases formed in the MOC paste...

The cause of frosting salt on the magnesia product surface was analysed in detail.Based on experimental research,Some measures for depressing frosting salt on the magnesia product surface were proposed.The research results indicated that electro chemical treatment of these products under the condition of adding various mixed modifying agents,the frosting phenomenon is obviously depressed.

MAGNESIUM oxychloride cement was discovered1 not long after portland cement. Its high water solubility has, however, effectively curtailed its use as a construction material except for non-structural interior applications. Nevertheless, the rapid setting and hardening properties of this cement, as well as its ability to accept large amounts of different fillers (for heat and sound insulation), are useful characteristics and are of interest to cement chemists in furthering their understanding of ...
