| 摘 要： | 为了研究氯氧镁水泥(MOC)试件分别在老卤、原卤、海水和淡水4种水环境中强度变化规律,本文以掺加一定量复合改性剂的MOC为基体,将其养护至28天后,分别置于老卤、原卤、海水和淡水中浸泡一定期龄,分析其在4种特定水环境中的强度变化规律。实验结果表明,MOC试件在4种特定水环境中抗压强度变化规律不同。相较于空气中养护,MOC在老卤、原卤、海水和淡水浸泡下,抗压强度逐渐降低,其抗压强度降低程度为老卤<原卤<海水<淡水。经4种特定水环境浸泡后,MOC抗压强度保留相在老卤中最高,其强度保留相高达95.60%,证明MOC试件在老卤中具有较好的抗盐卤腐蚀性能。

| Abstract: | In order to study the compressive strength development of magnesium oxychloride cement (MOC) in four water environment as aging brine, raw brine, seawater and freshwater, respectively. The study on the compressive strength development of MOC pastes mixed with composite addictive were carried on when immersed in the four water environment for specific period after 28 days air curing. The results show that the compressive strength development of MOC specimens varies in four kinds of specific environment. In comparison with immersed in air, the compressive strength of MOC pastes decreased steadily after aging brine, raw brine, seawater and freshwater immersion. The degree of compressive strength decreasing has the trend of aging brine
