The precision of the existing service life models for chloride exposed concrete structures is highly dependent on the chloride threshold values for the actual exposure conditions and binder compositions. Therefore, a reliable determination of the chloride threshold values for initiation of reinforcement corrosion in concrete structures becomes of paramount importance. A commonly accepted test method for determination of chloride threshold values does currently not exist. However, the RILEM TC 235-CTC group has recently agreed upon the experimental details of an accelerated test method based on open circuit measurements on rebars in concrete specimens exposed to a chloride solution, and an international Round Robin test has been initiated with the purpose of testing the suggested method. This paper presents experiences from our work with determination of chloride threshold values, as well as preliminary results from our participation in the Round Robin test initiated by RILEM TC 235-CTC.
