Abstract: | The accelerated chloride migration test in this study is a modified version of the ASTM C1202-97 or AASHTO T277-96 (RCPT) method. The current, chloride-ion concentration and temperature were measured during the experiment. Four different concretes used for test had a water to cementitious ratio of 0.4, containing various mineral admixtures. The transport properties were investigated using the accelerated chloride migration test. At a steady-state chloride flux, a good correlation was found between the charge passed (obtained by integrating the current-time curve) and the chloride-ion concentration. |
