摘要：Rebar corrosion not only reduces the section of rebar, but also the volume expansion produced by corrosion will cause the protective layer to crack in advance, and produces corrosion expansion crack. In this paper, the corrosion expansion process of concrete was analyzed by the equivalent perimeter hypothesis, the width where corrosion products flow into crack in the corrosion process was considered, the relationship between existing joint displacement and corrosion rate was corrected, moreover, the relationship of corrosion expansion crack and corrosion time and corrosion rate was established, compared with the existing data and the rationality of the model is proved.
