Abstract
Energy storage concrete was prepared by the paraffin wax of which the phase transition temperature is 26℃ as phase
change materials and porous lytag as adsorption carrier. Contrast test was prepared by the blank specimen in order to
research the energy storage ability in both warming and cooling system. Results showed that the heating and cooling
process of energy storage concrete were slower than that of the blank specimen. Paraffin wax phase change materials
play a certain role in the temperature adjustment function.
