Abstract：Complex service environments impose stringent demands on the long-term performance of concrete structures.Surface coating technology serves as a critical approach for enhancing the durability of concrete.This paper systematically summarized the technical principles and fabrication methodologies of concrete surface coatings from the perspectives of two protective mechanisms:film-forming sealing coating and penetration-enhanced coating.Subsequently,it elucidated the primary types and application performances of concrete surface coatings under three challenging service environments(severe cold,marine,and plateau).Furthermore,it discussed existing technical limitations and future development trends,aiming to furnish theoretical foundations and practical references for improving the service performance of concrete structures under complex environmental conditions.
