文摘

Microencapsulated phase change materials give high energy storage capacity concrete. Microcapsule addition increases the porosity of concrete. Thermal and mechanical properties are linked to the enhanced concrete porosity. Agglomerated microcapsules have strong impact on the concrete properties. Microcapsules caused geopolymer to become more energy efficient than Portland cement.
