摘  要:混凝土已被广泛应用于建筑、道路、桥梁、隧道、水利工程等各个领域中,其结构耐久性与本身渗透性紧密相关。然而在长期使用过程中,当外界腐蚀介质侵入混凝土内部,不可避免会造成混凝土性能劣化以及钢筋等腐蚀破坏。因此,需着重研发高性能防腐涂层,以提升混凝土服役耐久性,保障混凝土服役安全。就混凝土腐蚀机理及现阶段各类防腐蚀涂层的研究进展进行了综述。通过涂覆防腐涂层,可显著延长混凝土的使用寿命,增强其耐久性。高性能混凝土防腐涂层的研发与应用是工程安全保障领域重要的发展方向与需求,将为工程领域带来更多的可能性。Concrete has been widely used in various fields such as buildings,roads,bridges,tunnels,water conservancy projects,etc.,and its structural durability is closely related to its own permeability.However,in the process of long-term use,when the external corrosive medium invades the concrete,it will inevitably cause the deterioration of concrete performance and corrosion damage of steel bars.Therefore,it is necessary to focus on the research and development of high-performance anti-corrosion coatings to improve the durability of concrete service and ensure the safety of concrete service.The research progress of concrete corrosion mechanism and various anti-corrosion coatings at this stage was reviewed.By applying an anti-corrosion coating,the service life of concrete can be significantly extended and its durability enhanced.The research and development and application of high-performance concrete anticorrosive coatings is an important development direction and demand in the field of engineering safety assurance,which will bring more possibilities to the engineering field.
