BEHAVIOR AND PROTECTION OF HYDROGEN EMBRITTLEMENT ON TENDONS OF PC MEMBERS

This paper presents the results of a study on hydrogen embrittlement of prestressed concrete (PC) tendons. The purpose of research work is to make clear the influence of cathodic protection used in PC members. The tests consist of three series. Series A was carried out to evaluate the relationship between the polarization potential and the period of current supply. In Series B, a countermeasure to mitigate hydrogen embrittlement is investigated. PC members in Series C were cathodically protected and exposed to a sea environment for five years. This test program showed that the harmful effects of hydrogen embrittlement may be mitigated by switching off of the cathodic protection at regular periods.
