Application of Phase Change Material (PCM) in Concrete for Thermal Energy Storage
Phase Change Material (PCM) has the ability to absorb and to release a large amount of latent heat during its temperature-constant phase change process. This characteristic makes PCM an ideal candidate for building thermal energy storage (TES). The incorporation of phase change materials (PCMs) in building materials has attracted a lot of research interest due to the concern on energy efficiency. PCM-concrete can be used for reducing the building energy consumption and enhancing the comfort of the building. Significant research showed that PCM-concrete has better latent heat storage and thermal performance. In this paper, butyl stearate (BS), calcium chloride hexahydrate, and polyethylene glycol 600 were investigated as PCMs incorporating concrete. The PCMs consisting of butyl stearate and calcium chloride hexahydrate were successfully encapsulated by PMMA polymerization. The encapsulated PCMs were successfully incorporated into cement mortar. The thermal properties of encapsulated PCMs were studied by differential scanning calorimetry (DSC), transmission electron microscopy (TEM), and thermal conductivity analyzer. The mechanical properties of PCM-based concrete were tested according to Singapore Standards.
