ELECTROLYTIC PROTECTION METHOD FOR REINFORCED CONCRETE STRUCTURE

摘要

PURPOSE:To provide the electrolytic protection method for a reinforced concrete structure capable of easily evaluating the corrosion preventive effect of the reinforcing bars in electrolytically protected concrete even if a flame sprayed metallic film is in electrical contact with the reinforcing bars. CONSTITUTION:Monitoring steel products 5 formed by housing steel products into concrete 3 adjusted in a salt content so as to indicate the potential baser than the potential of the reinforcing bars are installed together with a reference electrode 7 near the reinforcing bars 2 in the method for electrolytically protecting the reinforcing bars 2 in the concrete structure 1 by a anodic system. The monitoring steel products 5 are back filled by concrete adjusted to almost the same salt content as the salt content of the concrete structure 1 and the potential difference between the steel products 4 and the reference electrode 7 is measured, by which the electrolytic protection effect is evaluated.
