摘要
本文主要介绍了氯氧镁水泥(MOC)混凝土的抗腐性能和在高寒、高盐渍地区工程应用的力学性能变化规律。根据研究发现,砂浆MOC和MOC混凝土经过老卤浸泡后,力学性能没有明显的降低,得到了很好的保留,MOC具有一定的抗盐卤腐蚀性能;从MOC混凝土的路面应用得到MOC混凝土在养护7 d即达到工程强度,满足工程应用标准,且其强度在盐渍地区保持相对稳定,证明了混凝土MOC的工程应用价值及应用于西部高寒和高盐渍地区的潜力和应用前景。
This paper mainly introduces the changes of mechanical properties of laboratory MOC concrete and engineering application concrete MOC in cold and salty areas. According to the research of MOC concrete, the mechanical properties of mortar MOC and concrete MOC have not been significantly reduced after being soaked by the aging brine, and they have been well retained. Therefore, MOC has good salt attack performance. From the application of concrete MOC pavement, it can be obtained that the MOC concrete meets the engineering strength within 3 days curing and it meets the engineering application standard, and its strength remains relatively stable in the saline area, which proves the engineering application value of concrete MOC and its potential and application prospect in high cold and salinity areas in the west.
