Corrosion Environment Evaluation for Infrastructure Maintenances

Abstract

With deterioration of infrastructure built for the rapid economic growth period, importance of the maintenance increases. The corrosion environment evaluation for the maintenances of the infrastructure was described. First of all, it was shown to be able to calculate concentration and thickness of water film formed on metal surface according to a sea salt and relative humidity. Next, the small coupon examination and the ACM sensor were taken up as an environmental evaluation technique. The measurement of the ACM sensor was explained as an application example in the steel bridge.
