| Abstract: | Through erosion test on five types of high-performance concrete in sulfate wet-dry cycle environment, the changes of concrete indicators including compressive strength, electric flux, and sulfate ion concentration after different wet-dry cycles are tested to analyze the erosion characteristics of sulfate wet-dry cycle on high-performance concrete. Finally, reasonable suggestions and measures for reinforcement of concrete durability are put forward. |

| Keywords: | high-performance concrete wet-dry cycle compressive strength electric flux sulfateion concentration |
