This study is to examine the combined deterioration of concrete in cold region. Especially, this study is to examine the influence of freezing- thawing action and deterioration of surface layer of concrete due to freezing- thawing action on the chloride penetration into concrete. From the results of this study, it was found that the chloride penetration into concrete under freezing- thawing environment became higher compare with that under constant temperature condition, however, it was judged that the influence of scaling of concrete on chloride penetration was low.
