Energy demand in the building particularly in summer during peak hours due to outdoor climate and lack of sufficient high thermal mass construction materials. Advanced materials are required to reduce the recurring energy demand of buildings. This peak-hour energy demand can be significantly reduced by using phase change materials (PCM). These PCMs may be incorporated into building components/ products in various ways. In this overview, the recent advances in the field of using different types of PCMs, parameters to be considered for building components, encapsulation of PCMs, and influence of PCMs on thermal and mechanical properties of construction materials are briefly discussed. Importantly, the behavior of MPCM in building components is concisely elaborated in an effective way.

“…Conversely, inorganic PCM, which includes salts like sodium sulfate, has higher heat conductivity but can have issues with leakage and corrosion [12]. The bene ts of organic and inorganic PCM are combined in eutectic mixtures and hybrid PCM blends [13], which provide customized phase transition temperatures and improved performance characteristics.…”

This study investigates the influence of Glycerin content, water-to-binder (w/b) ratio, and concrete grade on the thermal and mechanical properties of concrete incorporating Glycerin as a phase change material (PCM). M20, M30 and M40 grades of concrete were studied using 0.40, 0.45 and 0.50 w/b ratios. The amount of Glycerin varied from 0 %, 2.5 %, 5.0 %, 7.5 % to 10 % and compressive strength was studied on 7, 28, 56 and 90 days. The slump values decrease with increasing glycerin content, especially at higher w/b ratios, with M20 concrete exhibiting the lowest slump due to its lower grade. Maximum compressive strength is achieved at 5% glycerin content across all mix categories, with a w/b ratio of 0.45 yielding the highest strength. Glycerin content affects the thermal properties, while the w/b ratio significantly influences thermal conductivity. Glycerin content has the most significant impact on thermal diffusivity and specific heat capacity. The interaction between glycerin dose, w/b ratio, and concrete grade is analyzed using Response Surface Methodology (RSM), revealing complex dependencies among these factors. These findings contribute to understanding the behavior of glycerin-modified concrete and provide insights for optimizing its thermal and mechanical properties in construction applications.
