Currently we are witnessing a huge concern of society with the parameters of comfort of the
buildings and the energetic consumptions. It is known that there is a huge consumption of
non-renewable sources of energy. Thus, it is urgent to develop and explore ways to take
advantage of renewable sources of energy by improving the energy efficiency of buildings.
The mortars with incorporation of phase change materials (PCM) have the ability to regulate
the temperature inside buildings, contributing to the thermal comfort and reduction of the
use of heating and cooling equipment, using only the energy supplied by the sun. However,
the incorporation of phase change materials in mortars modifies its characteristics. The main
purpose of this study was mechanical and thermal characterization of mortars with
incorporation of PCM in mortars based in different binders. The binders studied were aerial
lime, hydraulic lime, gypsum and cement. For each type of binder a reference composition
(0% PCM) and a composition with incorporation of 40% of PCM were developed. It was
possible to observe that the incorporation of PCM in mortars caused differences in properties
such as workability, compressive strength, flexural strength and adhesion, however leads to
an improvement of thermal behavior.
