Water-to-Cement Ratio of Magnesium Oxychloride Cement Foam Concrete with Caustic Dolomite Powder

Magnesium oxychloride cement (MOC) foam concrete (MOCFC) is an air-hardening cementing material formed by mixing magnesium chloride solution (MgCl2) and light-burned magnesia (i.e., active MgO). In application, adding caustic dolomite powder into magnesite can reduce the MOCFC production cost. The brine content of MOC changes with incorporation powder. This study investigated relationship between mass percent concentration Baumé degree a after bischofite (MgCl2·6H2O) from salt lake was dissolved in water. proportional amount water bischofite, functional formula for water-to-cement ratio (W/C) mixed were deduced. verified as feasible preparing through experiment.
