Avaliação de manifestações patológicas de fachadas da Unipampa Campus Alegrete utilizando a termografia infravermelha

Abstract

The pathological manifestations arise from some mistake made in some phase of the construction process, for external facades that are exposed to the action of aggressive agents this becomes even more propitious to the appearance of these anomalies. The objective of this work was to survey the pathological manifestations of the external façades located at the Federal University of Pampa, Alegrete / RS campus. Four (4) facades were selected taking into account their solar position. Photographic surveys were done using a conventional camera, and in addition, digital thermography was used to identify occult pathological anomalies, which is a nondestructive technique to evaluate building problems. The suggested methodology consists in identifying, quantifying and classifying the various existing pathologies, trying to understand the reason for the appearance of these anomalies. With the obtained results, it can be concluded that the most recurrent pathologies in this type of structure are: fissures (mainly horizontal, vertical and mapped), spots caused by humidity, efflorescence and disintegration of the paint.
