摘要：

The microbial corrosion of concrete not only causes the calcium hydroxide in the concrete to react with the biogenic sulfuric acid formed by the microbial metabolism to form gypsum and ettringite, but also decomposes the C-S-H in the concrete to produce insoluble and non-cementation colloids, therefore the performance of concrete will be degradated gradually. The development of microbial corrosion, including the aspects of microbial corrosion mechanism, influencing factors (materials and environmental factors), evaluation index (corrosion rate, H2S absorption rate, chemical composition) and preventive techniques(concrete modification, protective coating and biological killing technique) of concrete are elaborated in this paper to raise the concern of domestic scho-lars on the microbial-induced corrosion of concrete. © 2018, Materials Review Magazine.
