Abstract:

In order to evaluate the infuluence of pre-embedded phase change materials(PCM)for the inner temperature rise of a concrete, a semiadiabatic device was adopted to measure the  inner temperature change of a common concrete specimen and the concrete specimen with  pre-embedded PCM at different hydration ages, and the cooling influence factors of pre-embedded PCM were calculated and analyzed. The results showed that  the inner temperature of concrete that had pre-embedded PCM was related to the pre-embedded content and the specific heat of PCM, the phase transition heat and phase transition temperature of PCM, the dosage of cement materials per unit volume, the hydration heat of the cement, the specific heat, density and initial temperature of the concrete. The peak of inner temperature was reduced and the appearance time of the temperature peak was prolonged after the PCM was pre-embedded into the concrete specimen, while the inner temperature of concrete over long a period  could not be reduced.

Key words: phase change material, preembedded, concrete, hydration heat, inner temperature rise
