Abstract：Concrete has been widelyused in various fields such asbuildings，roads，bridges，tunnels，water conservancy projects，etc.，anditsstructural drabilityiscloselyrelated to itsown permeability.However，inthe processof long-term use，when the external corosive medium invades theconcrete，it will inevitably cause the deterioration of concrete performanceand corrosion damage of steel bars.Therefore，it is necessryto focus ontheresearchanddevelopment 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-corosion coatings atthis stage wasreviewed.By applying an anti-corrosioncoating，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.
