Focusing on two reinforced concrete specimens with different structures, performs thermal storage experiments in the two conditions that the temperature of the constant temperature environmental chamber remains at 36 ℃ and 31 ℃ respectively, and obtains the hourly temperature field of each measuring point inside the two specimens in 72 hours. The results indicate that the heat transfer between specimens and the surrounding air can be treated approximately as a one-dimensional process; in the same condition, the heat storage capacity ratio of the steel-finned specimen on the heat transfer surface is larger by eight percent than that of the unfinned specimen; the larger the heat transfer temperature difference between specimens and the surrounding air is, the better the improving effect of the fins on thermal storage of the specimen in 72 hours is.
