Abstract

In this study, two composite phase change materials (CPCMs) were prepared by using two different phase change materials (PCMs) as matrix combined with expanded perlite (EP) adsorption, respectively. To enhance the cyclic stability of the CPCMs, their surfaces were encapsulated and then mixed with building cement to create a novel phase change concrete, aiming to improve the safety and stability of concrete subgrades under temperature fluctuations. The adsorption properties, physical and chemical characteristics, energy storage capabilities, thermal stability, and encapsulation effects of the two CPCMs were comprehensively analyzed. Additionally, the mechanical and thermal properties of the two phase change concretes were tested and evaluated. The results demonstrated good physical adsorption and chemical compatibility between EP and both PCMs. The epoxy resin-encapsulated composite PCMs (ER-CPCMs) showed strong cyclic stability. The developed phase change concretes effectively mitigated the thermal shock effects caused by temperature increases on road subgrades.
