内容記述タイプ Abstract
内容記述 The purpose of this study is to examine how durability can be evaluated and deterioration estimated for reinforced concrete structual members in a cold environment. Under such conditions, concrete components suffer frost damage and steel corrosion. Model specimens of size 10×10×40 cm were developed ; these are suitable for rapid freez-thaw tests according to ASTM C 666, exposure testing, and load testing. Case studies were carried out in which many external factors. From the data obtained, an evaluation of the durability of concrete was induced by using a reliability function (R(t)). In the case of a water-cement ratio of 45 %,the reliability in the case of set-up ratio to initial ultimate strength becomes unreliable ? that is,the reliability falls below the assumed set-up ratio of 0.95 by neary 0.85%?at about 300 cycles.  In the case of a water-cement ratio of 45 %,the reliability in the case of set-up ratio to initial ultrasonic velocity becomes unreliable?that is, the reliability falls below the assumed set-up ratio of 0.90 by neary 70%?at about 300 cycles. Thus,the durability of cocrete is influenced by the number of freeze-thaw cycles.
