Heat Evaluation System in Concrete Considering Evaporation Heat

When the moisture in concrete member evaporates by high temperature, the evaporation heat which absorbs surrounding temperature occurs. The incremental rate of the internal temperature in concrete is reduced due to the evaporation heat in spite of continuously increasing external temperature. Therefore, this paper has proposed the evaluation algorithm for predicting the internal temperature of concrete members considering the evaporation heat under the high temperature. Finite element method is employed to facilitate thermal analysis for any position of member. To demonstrate the validity of this numerical procedure, the prediction by the proposed algorithm is compared with the test results of other researchers. The proposed algorithm shows a good agreement with the experimental results including the phenomenon that temperature is lost by the evaporation heat.
