Abstract:
Thermal insulation and thermal energy storage are becoming more and more attractive for residential and industrial buildings due to the need of sustainable development. The economical and efficient technique that can be used to produce building products for insulation and store energy is also the subject of research for a long time. Cement-based products manufactured by extrusion technique offer advantages in terms of the flexibility of section profiles, material performance enhancement and mass production mode. Different fillers can be used to achieve desired effects on thermal, mechanical and physical characteristics during extrusion process. These fillers include sand and expanded perlite which are good at thermal insulation and phase change composites which can provide high energy storage capacities. It is foreseeable that extruded building products with suitable fillers have potentiality for economical applications for thermal insulation and thermal storage of different kinds of buildings.
