Durability of concrete shaft wall has seriously endangered the safety of mining in salt environment.Based on the background of Tongting Coal Mine project, the corrosion behavior of concrete under structural loads was studied.In order to simulate the practice of shaft lining concrete, accelerated corrosion of concrete tests are adopted to simulate the real corrosion environment of concrete, and using the ultrasonic detection method, which could obtain the evolution law of the corrosion thickness of concrete by the time.Through micro structure images, quantitative explication of concrete corrosion thickness is analyzed.Compared with the experimental results, the factors of concrete corrosion are discussed.
