Abstract—In this study, the Paraffin/Silicon dioxide phase change materials PCM was mixed into the aerated concrete to prepare thermal storage aerated concrete. The thermal performance, compressive strength, dry density and thermal conductivity were measured. The microstructure of the thermal storage aerated concrete was observed with a Scanning Electron Microscope. The results showed that the compressive strength of the thermal storage aerated concrete was decreased with the increase of the amount of the composite PCM. The existence of composite PCMs makes the crystallinity of the tobermorite decreased. The aerated concrete with the composite PCM shows notable thermal storage performance.
