However most concrete structures in cold regions are influenced by freezing and thawing in air. The purpose of this study is to evaluate the durability of reinforced concrete under the influence of rapid freezing and thawing in air. The specimens are reinforced concrete models(RC model specimens)of size 10\u00d710\u00d740 cm. The results of rapid freeze-thaw tests in air indicate that concrete specimens with a water-cement ratio of 65\uff05 deteriorate more than specimens with lower water-cement ratios.\u3000Further\uff0cthe durability of concrete with a high water-cement ratio\uff0csuch as 65\uff05\uff0cbegins to decrease after 2800 freeze-thaw cycles in air.
