Abstract

　In this research, the estimation method of the convective heat transfer coefficient of concrete was examined. The estimation method of the convective heat transfer coefficient, was done by a back analytical technique which used the result of an easy temperature measurement, in the construction site. First of all, the objective function in a back analytical technique was examined by using the measurement temperature in the RC box culvert. Next, the temperature measurement, condition in the construction site was examined from the result of applying the objective function which had examined it, to two kinds of concrete specimens with a different size. And, the temperature of the mass concrete or the same mixing as a concrete specimen was analyzed, and the effectiveness of the identification value of the convective heat transfer coefficient was verified. As a result of a series of research, the effectiveness of the estimation method of the convective heat transfer coefficient proposal by this research was able to be confirmed.
