121 Experimental Study of Thermal Behavior of Non structural Lightweight Concrete Panels Incorporating Shape Stabilized Phase Change Materials SSPCMs By Sahar Mokhtari sahar mokhtari@cv iut ac ir Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Dr Morteza Madhkhan Email madhkhan@cc iut ac irAbstractEconomical fast growth worldwide has led to an increase in energy demand Energyimprovement in buildings has not only reduced our dependence on fossil fuels but also hasa significant effect on emission of greenhouse gases The application of phase changematerials in construction of buliding materials and building elements is one of the newestand the most effective methods for thermal energy storage in buildings In this study at first different materials were tested and silica fume was selected as the best stabilizer Shape stabilized phase change material SSPCM was produced without any leakage in alternatingthermal cycles using PEG 600 and silica fume Then thermal performance and thermalenergy storage capability of the filled and hollowcore specimens with thickness of 10 and15 cm including SSPCMs with 10 and 18 percents and macroencapsulated PCMs wereinvestigated The specimens were tested under the weather temperature condition of asummer day of Ardabil and Isfahan Maximum reduction of inner side temperature and thereduction of ultimate inner side temperature and time delay to reach to the maximumtemperature were measured as the thermal performance criteria Moreover compressive andtensile strengths of the specimens including shape stabilized phase change materials SSPCMs were measured Results stated that the application of phase change materials inthe specimens would reduce the inner side temperature of the concrete walls up to 7 2 andup to 9 5 hour shift in peak load with respect to the type of specimen The specimens withmacroencapsulated PEG showed the most reduction in the inner side temperature and thespecimens with less thickness had a better thermal performance Furthermore the presenceof silica fume in shape stabilized phase change materials compensates the reduction of
