  • The study presented in this paper focuses on an experimental investigation of cement

    mortar incorporated lauric acid/expanded perlite phase-change materials (PCMs). The

    physical properties of mortar incorporated shape-stable PCMs (SSPCMs) were evaluated.

    The results showed that the addition of SSPCM increased the water absorption of mortar,

    reduced the bulk density, and thermal conductivity coefficient of SSPCM mortar.

    Microstructure was studied for SSPCM composite in mortar. Scanning electron microscope

    (SEM) imaging indicated that most SSPCM granular particles were evenly distributed into

    the cement matrix after the mechanical strength test, and the SSPCM are in good bond with

    the cement binder. The temperature-control test revealed that the temperature adjustment

    properties of samples incorporating SSPCM was significantly greater than that of the

    reference mortar, and SSPCM-integrated mortar is thermally reliable because of the fact that

    the SSPCM mortars showed no degradation in thermal performance after multiple thermal

    cycles.
