RESEARCH PROGRESS OF THIOBACILLUS CORROSION ON CONCRETE

Thiobacillus corrosion is an important problem in sewer environment.The research progresses of thiobacillus corrosion on concrete in recent years are reviewed,and the corrosion mechanism is also introduced.The research of thiobacillus corrosion on concrete can be roughly divided into two groups:bacteria simulation tests and exposure tests in situ.In addition,the distinction between sulfuric acid corrosion and thiobacillus corrosion is explained.Though some advances have been made so far,there are a lot of void in the study of concrete corrosion resulted from thiobacillus.Especially the grading of the corrosion,the models for predicting corrosion rate should be intensified as soon as possible.
