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.

这项研究是为了检查寒冷区域混凝土的综合恶化。尤其是，这项研究是为了检查冰冻作用和由于冰冻作用对氯化物渗透到混凝土的冻结作用而导致混凝土表面层的影响。从这项研究的结果中可以发现，在冰冻环境下，氯化物渗透到混凝土中变得更高，但是与恒温条件下的氯化物相比，氯化物的渗透率较高，但是，据认为，混凝土缩放对氯化物渗透的影响较低。
