A preliminary study on the increased thermal capacity in thermal energy storage concrete solids with inclusions of phase change materials is presented here. Particularly, the change in the thermal behavior of such composites, by varying the inclusions percentage, is evaluated. An ad hoc hygrothermal finite-element code has been developed, able to evaluate the nonlinear concrete behavior during the phase changes of phase change materials (PCM), subjected to a load history of the test plant designed by ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development). Transient thermal analyses have been conducted, assuming a homogeneous distribution of phase change materials within the cementitious matrix. Hygro-thermo-mechanical models have been developed to evaluate the heat storage capacity of the composite material, and its change in mechanical strength has been analytically and numerically investigated, both at environmental temperature and during heating. The adopted code takes into account a homogenized composite, having a uniform distribution of PCM within the cementitious matrix and characterized by homogenized hygrothermal properties.
