N2  - This paper dedicates to investigate the internal
microstructure and thermal performance of a thermal
energy storage building material, namely geopolymer
concrete containing encapsulated phase change
materials (GPC-PCMs). X-ray micro-computed
tomography (micro-CT) was introduced to characterise
the internal microstructure of the proposed concrete
material, while the thermal performance of the concrete
material was evaluated by a model consisting of microCT sample scanning, finite element analysis (FEA) sample
modelling and computational fluid dynamics (CFD)
thermal simulation. It is found that the PCM
encapsulated by dip-coating technique exhibits good
quality during concrete mixing and curing. Even PCM
distribution and favoured PCM/GPC compactibility were
observed in the proposed GPC-PCM sample. In addition,
a slightly higher air void content was resulted by the
incorporation of PCM. The thermal performance of the
suggested concrete material in terms of thermal
insulation and thermal energy storage was improved
considerably after incorporating the suggested PCM.
