Study on Properties of Paraffin Phase Change Energy Storage Concrete

AbstractEnergy storage concrete was prepared by the paraffin wax of which the phase transition temperature is 26̊C 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
