要旨 In order to investigate the electrochemical properties of sheath-grout-tendon (SGT) element in post-tentioned PC bridge, five SGT specimens with various grouting degrees/styles were tested in tap water by half-cell potential (HCP) and electrochemical impedance spectroscopy (EIS) method. It is concluded that corrosion status of galvanized steel sheaths can be determined by HCP method, but not the inner tendons due to the shielding effect. Grouting degrees can be evaluated by fitting measured EIS data to the equivalent circuits provided that no electrical connection exists between sheath and PC tendon.
