Abstract
nThis investigation delves into improving building thermal comfort using microencapsulated phase change materials (PCM@SiO2) in cement mortar. The encapsulation process, achieved via a sol-gel method, envelops PCM in a silicate shell Differential Scanning Calorimetry (DSC) and Fourier-Transform Infrared Spectroscopy (FTIR) were used to confirm the thermal properties and integrity of encapsulated PCM, which showed an encapsulation efficiency of 92.7% and a thermal storage capacity of 99.7%. The study involved the integration of PCM@SiO2 into cement mortar using a binder-to-sand ratio of 1:3. The PCM@SiO2 was varied in concentrations ranging from 0% to 20%, with increments of 5%. The mechanical strength and thermal conductivity of these PCM@SiO2 cement mortar mixes were meticulously evaluated. Findings revealed that while the addition of PCM@SiO2 marginally compromised the mortar’s mechanical strength, it substantially boosted thermal performance. This enhancement underscores PCM@SiO2’s utility as a multifunctional building material, harmonizing structural resilience with augmented thermal energy storage capabilities, showcasing its potential to significantly elevate the energy efficiency and comfort of modern buildings
