Opis

Incorporations of phase change materials (PCM) inbuilding materials have been proved to be feasible to exploithigh thermal storage capability of PCM to solve global energy andenvironmental problems we face. In this study, rheologicalbehaviors of fresh fiber reinforced cementitious composites were investigatedthrough using squeeze flow or upsetting test, stress relaxation anddigital image processing technique in order to make extrusionprocess smooth and successful. And short fiber reinforcedcementitious panels incorporated with granular phase change compositeshave been manufactured by the extrusion technique which cansignificantly improve the mechanical performance of cementcomposites. The thermal behaviors of extruded panels wereinvestigated by one-dimensional heat conduction and simulated-room tests.It was shown that both heat capacity and thermal inertiawere largely improved. The experimental results demonstrated thatthere could be a great potential for applying extruded thermalenergy-storing panels in building constructions to improve energyefficiency.
