Abstract
An evaluation on anti-corrosion behavior of galvanized rebar, subjected to different corrosion acceleration (series1) and galvanic corrosion (series2), was carried out. Accelerated corrosion test with relatively lower anodic polarization rate and segmented rebar was used which simulated galvanic couple by ordinary rebar. In series1, galvanized rebar showed 1/4 times lower actual corrosion amount than designed one by corrosion test and no corrosion of substrate was found which implies continuous anti-corrosion effect of zinc. In series2, galvanic corrosion was generated on segmented rebar which was placed in the farthest from ordinary rebar. Moreover, formation of anodic current of macrocell was identified.
