In this research, the form-stable composite phase change material was developed by incorporating paraffin on recycle block concrete (RB) through the vacuum impregnation method. The compatibility and thermal properties of RB impregnated with paraffin ranging from 0-35 wt% were characterized by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). Results revealed that paraffin was uniformly absorbed in RB with a good physical compatibility. The optimum adsorption ratio of paraffin in RB was 25 wt% which produced phase transition temperature of 52.85 OC and latent heat of 30.98 J/g. The obtained form-stable paraffin/RB composite PCM had proper latent heat and phase transition temperature and can be applied for thermal energy storage applications such as solar heating and cooling in buildings.
