本项目牵头单位为中山大学，联合合作单位为澳门大学，该项目聚焦我国南海海工混凝土结构的过早腐蚀破坏问题，从钢筋表面钝化膜构筑、混凝土内Cl^-捕获及外隔离层三个层面建构协同防护体系，有利于在南海严酷复杂海洋环境下海工混凝土的钢筋锈蚀与协同防护机制方面取得突破，为发展和建设海洋工程、推进和实施国家海洋战略提供支撑。

The leading unit of this project is Sun Yat-sen University, in collaboration with the University of Macau. The project focuses on the issue of premature corrosion damage to offshore concrete structures in the collaborative protection system through three aspects: passivation film construction on the surface of steel bars, chloride capture within concrete, and external isolation layer. This breakthrough will be beneficial for effectively addressing steel bar corrosion and implementing a coordinated protection mechanism for offshore concrete structures in the harsh and complex marine environment of the South China Sea. It will provide support for the development and construction of marine engineering projects as well as promote and implement national maritime strategies.
