urrently, it is necessary to study and develop constructive
solutions with high durability, in order to deacrese the
environmental negative impacts and maintenance costs
of buildings. The development of functional construction
materials to increase the energy efficiency of buildings is
now an effective way to contribute to a more sustainable
development. The high energy consumption throughout the
world is one of the main problems of the modern society.
Thus, the development of mortars with incorporation of
phase change materials (PCM) is a very promising technique
for the improvement of social, economic and environmental
habitability conditions.
The PCM have the thermal regulation capacity due to their
ability to absorb and release energy to the environment,
allowing decrease the energy buildings consumption, gas
emissionstotheatmosphere,environmentalnegative impacts
and increase the energy efficiency of buildings. The durability
study depends on the costruction materials application. The
exterior solutions have more requirements compared to the
interior solutions, since they are more exposed to weather
conditions. However, the interior construction solutions must
also be extensively studied regarding to their durability, more
specifically their behavior at lowand high temperatures. Thus,
it is important to evaluate the behavior of PCMmortars when
submitted to the freze-thawn cycles (-18
o
C - 20
o
C) and high
temperatures actions ( 200
o
C, 400
o
C and 600
o
C). The main
results obtained with this study allow to conclude that the
incorporation of PCM leads to identical behavior to mortars
without PCM.
