摘要	Anti-corrosion cement is urgently needed due to the rapid development of salt lake and marine engineering facilities, and ordinary Portland cement (OPC) concrete will undergo significant corrosion in salt environments. Due to its unique composition, magnesium oxychloride cement (MOC) has the potential to replace OPC in salt environments. In this work, the corrosion resistance of MOC in different salt environments was investigated. The results showed that the compressive strength and main hydration products in the MOC were stable in high salt environments. Moreover, the MOC exhibited excellent corrosion resistance in aging and raw brine solutions. In low salt environments, the compressive strength steadily decreased, and the main hydration products decomposed, indicating poor corrosion resistance in seawater and freshwater. In addition, the MOC mainly exhibited physical salt crystallization in high salt environments and chemical reactions in low salt environments.
