Microbial corrosion of concrete (MICC) is still a problem in concrete engineering. The H2S and some sulfur compounds in the sewer pipe are oxidized by sulfur oxidizing bacteria to produce biological sulfuric acid, which reacts with the calcium-rich phase in concrete to form gypsum and expansive ettringite and decomposes hydrated calcium silicate formation of insoluble and non-cemented colloids, thus leading to the deterioration of concrete. This review mainly represented recent research work on MICC aspects, including microbial corrosion mechanism, influencing factors, test methods, evaluation indexes and protection measures of concrete as well.
