摘　　要：研究了养护温度、氯化镁溶液浓度、氧化镁/氯化镁摩尔比对氯氧镁水泥(以下简称镁水泥)28 d抗压强度和软化系数的影响,通过改变单一变量探讨了个因素对镁水泥性能的影响规律。结果表明:随着养护温度的提高,镁水泥的28 d抗压强度逐渐降低,28 d软化系数逐渐升高;随着MgCl_2浓度和MgO/MgCl_2摩尔比的增大,镁水泥28d抗压强度先升高后降低,28 d软化系数先降低后升高。Some factors were studied the influence on the 28 d compressive strength and softening coefficient of Magnesium Oxychloride Cement （MOC） , included curing temperature, MgCl2 concentration and MgO/MgCl2 mole ratio, the rules of all factors impact on MOC properties were discussed by alter single factor. Results show that, as the curing temperature increasing, the 28 d compressive strength of MOC declined, and softening coefficient increased gradually. As the increasing of curing temperature and MgO/MgCl2 mole ratio, the MOC 28 d compressive strength increased first and then decreased, and the softening coefficient opposite.
