Magnesium oxychloride cement-based composites for latent heat storage: The effect of the introduction of multi-walled carbon nanotubes

Original language description

Due to the energy crisis, energy savings in construction are very important. One possibility is the incorporation of phase change materials (PCM) into construction materials. In this paper, PCM was introduced into magnesium oxychloride cement (MOC) together with multi-walled carbon nanotubes (CNT) to form multicomponent MOC-CNT-PCM composite for latent heat storage. The phase composition, chemical composition, and microstructure of prepared composites were analyzed in detail. The focus was also given to thermal stability, which was evaluated by Simultaneous Thermal Analysis combined with Mass Spectroscopy. The enthalpies of phase changes were analyzed by Differential Scanning Calorimetry. On matured samples, structural, mechanical, hygric, and thermal properties were tested and the influence of CNT addition was evaluated. Despite the introduction of PCM causing significant deterioration of mechanical parameters of the prepared construction composites, the mechanical strength regarding their possible utilization in low-energy buildings was proven to be sufficient. The relative decrease in the mechanical parameters was also compensated by excellent thermal properties that will allow for a decrease in energy consumption attributed to the production and utilization of such buildings. © 2023 Elsevier Ltd
