Abstract

In this paper, an experiment was performed to measure the rebar corrosion rate of carbonated reinforced concrete specimens with different cover thickness and carbonation depth parameters, exposed to several different humidity environments. As a result, the moisture content affects the corrosion rate of rebars rather than the cover thickness and the carbonation depth. The experimental results were compared with the relationship between the moisture content and the corrosion rate of rebars measured in the existing reinforced concrete building survey.
