Abstract: Phase change materials (PCMs) are an attractive solution for reducing energy usage because of their efficient latent heat storage abilities. This paper examined chemical and physical properties of micro-PCMs before and after their integration with concrete samples. A Thermal Constants Analyser (TPS) measured the thermal conductivity of the PCM-concrete using the transient plane source (TPS) method. Results showed that overall, the thermal conductivity of the concrete was unchanged after the addition of the PCMs, likely due to the small concentrations of PCMs and their low thermal conductivity.
