Mechanical and thermophysical properties of cement mortars including bio-based microencapsulated phase change materials
Highlights A liquid dispersion of bio-based microencapsulated PCM is added to cement mortars. The mixing protocol provides uniform mPCM distribution and prevents particle damage. mPCM mortars show reduced mechanical strength but much improved thermal resistance. Good balance of mechanical and thermal properties is achieved with 8 wt% mPCMs.
Abstract This study investigates the mechanical and thermophysical performance of cement mortars incorporating microencapsulated phase change materials (mPCMs), which consist of an aqueous dispersion of 100% bio-based fine core–shell particles. A specific protocol was used to manufacture the mortar samples, which ensures a homogeneous particle distribution and prevents microcapsule leakage. The addition of mPCMs to the mortar causes both a decrease in density, an increase in porosity, and a substantial loss of mechanical strength. Conversely, hot-disk characterization revealed a large improvement in the thermal performance. The system containing 8 wt% mPCMs exhibits a good balance between its mechanical and thermal properties.
