| Outline of Final Research Achievements |
In this study, to develop a preventing corrosion progress method for unpainted weathering steel with sever corrosion damages, material characteristics of casting Al-Zn alloy plate as a sacrificial anode and fiber sheet which has functions of continual water absorption and retention were clarified. In addition, the applicability was also investigated by applying the method to an I-section steel girder bridge of which paint coating has deteriorated and disappeared.
