Sulfate-aluminate cement has been extensively utilized in marine engineering due to its exceptional resistance to sulfate corrosion. However, prolonged exposure to seawater leads to reduced durability of this cement, primarily manifested as corrosion of cement matrix materials and structural failure. This study investigates factors affecting the durability of sulfate-aluminate cement, including chloride ions, sulfates, and other chemical components in seawater, while analyzing the mechanisms of corrosion processes. Based on these findings, several corrosion inhibition strategies are proposed, such as optimizing cement mix proportions, applying external corrosion inhibitors, and implementing surface treatment technologies. These measures aim to enhance the long-term performance and durability of sulfate-aluminate cement in marine environments.
