Abstract
We employ a numerical methodology to predict the freeze-thaw performance of cementitious composites containing lightweight aggregates (LWAs) impregnated with phase change material (PCM) as thermal energy storage (TES) agent. The governing equation for heat transfer is combined with homogenization techniques to predict the temperature and associated heat flow for cementitious materials during the phase transition of the PCM. The material properties of the cementitious composite and heat dissipation behavior during thermal cycling were characterized using a small-scale longitudinal guarded comparative calorimeter (LGCC) test. Phase transitions associated with freezing/melting of PCM occurs gradually over a narrow temperature range. Pore size effect of LWA on freezing and melting behavior of PCM was found to be relatively small. This approach is extended to the prediction of the thermal energy storage capacity of PCM on improving the freeze-thaw performance of concrete specimens exposed to realistic thermal conditions at various locations in the United States.
