| Abstract: | Macro, quantitative and predictive methods for studying corrosive degrees of rebars in concrete members are proposed by observing 180 specimens of three types and testing 258 broken rebars; a related expression between corrosion of rebar and width of longitudinal crack,cover thickness, diameter of rebar and concrete strength is obtained, so a scientific basis is provided for the durability estimation and the reliability appraisal of concrete structures. |

| Keywords: | corrosion of rebar test width of longitudinal crack prediction |
