Thermal energy storage characterization of cement-based systems containing microencapsulated-PCMs
Highlights Thermal Energy Storage (TES) capacity of cement paste systems with MPCMs is investigated. DSC results, thermal conductivities and mechanical tests are presented and discussed. A new experimental TES technique based on the use of spherical samples is proposed. Numerical simulations based on an enthalpy-based method have been performed.
Abstract This work reports a detailed experimental study that is aimed at investigating the Thermal Energy Storage (TES) performance of cementitious systems containing Microencapsulated Phase Change Materials (MPCMs). New spherical-shaped test specimens for TES measurements were produced following an innovative casting technique, developed at the Institut für Werkstoffe im Bauwesen – TU Darmstadt. Three water-to-cement ratios and three MPCMs volume fractions, leading to a total of nine different mixtures, were investigated. The thermal experiments were accompanied by mechanical tests to observe the effect MPCMs have on the resulting strengths in both compression and bending. The analysis and discussion of the TES results are employed for calibrating an enthalpy-based model. The experimental data have been applied to evaluate the corresponding temperature-based material parameters like specific heat, conductivity, or more in general, the energy storage capacity of a system under transient heat conduction conditions.
