Abstract:

Phase Change Materials offer the benefit of energy storage through latent heat while requiring less volume compared to alternative thermal storage materials. This study evaluates the compressive strength of cement mortar incorporating Phase Change Materials within building envelope applications. The inert mortar composition of Phase Change Materials (PCMs) facilitates the phase transition between solid and liquid states due to its inherent properties. This study utilises gypsum powder (G) combined with paraffin wax to create PCM aggregates, which serve as a replacement for fine aggregates in cement mortar. The production of gypsum-based PCM cement mortar was accomplished by combining quartz sand, gypsum, and PCM aggregates with water. This was done in order to make use of PPC cement. For the purpose of achieving the optimal needed strength properties of the mortar, an investigation was conducted into the variation in strength qualities that occurred with varied mix proportions of gypsum with PCM aggregates in relation to quartz sand.
