Resumen:
This work reports a detailed experimental campaign aimed at investigating the thermal behaviour of porous cementitious systems containing Microencapsulated (M-)PCMs. Test specimens for thermal energy storage measurements were produced by following a new spherical-shaped casting technique, developed at the Institut für Werkstoffe im Bauwesen ? TU Darmstadt. Thermal analysis in such mentioned spherical specimens was used for characterizing the materials under investigation. Three water-to-cement ratios and three MPCMs volume fractions, for a total of nine different considered mixtures, were investigated. The experimental campaign was also completed by performing mechanical tests aimed at observing the effects of the PCMs on the resulting strengths in both compression and bending. The study proposes a novel approach to determinate the energy storage capacity of MPCM cement paste systems as a basis for modelling. The analysis and discussion of the results will be employed for calibrating a 1D model and to evaluate the temperature-based thermal parameters like specific heat, conductivity or more in general the energy storage capacity of the system under transient heat conduction conditions.
