Abstract
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.
