The Effect of Doping High Volume Magnesium Sulfate on Properties of Magnesium Oxychloride Cement

چکیده
The composite gelling system of chlorine and magnesium thioxide was prepared by mixing different mass fractions sulfate solution into MOC. Detailed studies regarding the influences replacing chloride on setting time, compressive strength, water resistance oxychloride cement (MOC) have been carried out in this paper. phase composition micro morphology hydration products mixed were analyzed XRD SEM. results show that addition prolongs time reduces strength Compared with primordial MOC system, improved, exhibiting optimal when fraction 30%. phases composed 5Mg(OH)2·MgCl2·8H2O 5Mg(OH)2·MgSO4·7H2O phases. microscopic shows interior air-cured a large number needle-like crystals, continuous crystal structures close contact strong bonding force. Cracks pores appear surface after submerging water, crystallization state internal crystals becomes worse. stability closely related to morphology.
