Abstract:Besides the reason of structure, the disease of concrete bridges is mostly caused by degeneration of material property, which includes degeneration of concrete property and corrosion of the reinforcing steel bar in concrete. It summarizes the present situation and the development of disease evaluation and protective technology of reinforced concrete bridges. It brings forward to evaluate and diagnose the disease of reinforced concrete bridges through analyzing the degeneration of material property.
Keywords:Reinforced concrete bridge  Disease  Property degeneration  Protection  Evaluation  Summary
