In the present work, the experimental and theoretical analysis of hybrid cement mortar embedding microencapsulated PCMs is reported. Different samples with variable PCM loading, up to 15 wt.%, were prepared and experimentally tested by means of a properly designed and realized setup, able to compare the dynamic thermal behaviour of two sample contemporary. The results demonstrated that the mixed PCM samples are characterized by higher overall thermal capacity, which allows limiting the temperature fluctuation if compared to standard pure cement mortar sample. Furthermore, a numerical model was implemented in COMSOL Multiphysics and satisfactorily validated by means of the experimental results. The validated model will be then employed to simulate full-scale building configurations making use of the proposed hybrid cement mortar - PCM.

Abstract
In the present work, the experimental and theoretical analysis of hybrid cement mortar embedding microencapsulated PCMs is reported. Different samples with variable PCM loading, up to 15 wt.%, were prepared and experimentally tested by means of a properly designed and realized setup, able to compare the dynamic thermal behaviour of two sample contemporary. The results demonstrated that the mixed PCM samples are characterized by higher overall thermal capacity, which allows limiting the temperature fluctuation if compared to standard pure cement mortar sample. Furthermore, a numerical model was implemented in COMSOL Multiphysics and satisfactorily validated by means of the experimental results. The validated model will be then employed to simulate full-scale building configurations making use of the proposed hybrid cement mortar - PCM.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
