Temperature History of Inner-form and Re-bars in Aluminum Concrete form During a Cold Weather Condition

한중 환경에서 알루미늄 폼 내부 철근의 직경변화에 따른 온도 특성

This study is to investigate the effect of the diameter of reinforcement bars located in an aluminum-form on the temperature histories of the re-bars before placing concrete during a cold weather condition. The diameters of reinforcement bars with 13 mm, 19 mm, 25 mm and 32 mm were prepared for the experimental tests. Results showed that the larger the size of the diameter of the bars, the higher were the temperature drop. However, this study found that its effect on the temperature drop of the bars was insignificant.
