PREPARATION and PERFORMANCE of COMPOSITE BUILDING MATERIALS with PHASE CHANGE MATERIAL for THERMAL STORAGE
چکیده انگلیسی
The polyethylene glycol (PEG-1000) was selected as phase change material (PCM) and the expanded perlite (EP), the granular activated carbon(GAC), the powdered activated carbon (PAC) and the expanded graphite (EG) were selected as porous adsorption materials. The composite phase change material (CPCM) was prepared by the physical adsorption method. The composite phase change materials compound with the polyethylene glycol and the expanded graphite were picked by comparing and analyzing the adsorption capacity of such four types of porous materials. And then the composite building material for thermal storage mixed with the CPCM and the cement, water-reducer, early strength agent was prepared in the pressure condition of -0.05Mpa and the constant temperature condition of 70℃. Its thermal physical properties, the structural stability and the compression resistance capability of different quality proportion specimens were experimental researched. The results show that such composite building materials with CPCM appears light density, high thermal conductivity, large heat storage capacity and good stability, and its compression resistance capability can satisfy the requirement of ordinary mortar building material.
