Identificação das principais manifestações patológicas de ambientes internos em uso: estudo de caso em uma edificação da UTFPR campus Pato Branco

Abstract

Constructions are subject to the appearance of pathological manifestations, whether due to natural aging, the influence of the environment in which they are inserted, how they are used, or even failures and bad choices during their elaboration. The appearance of these defects reflects on the functionality of the building, impairing its performance and useful life. The study of pathological manifestations is dedicated to understanding the mechanisms involved in their occurrence in order to achieve a correction that restores the comfort and durability of the building. Thus, this work seeks, through a case study, to identify the main pathological manifestations present in the internal coatings of a building of the Federal Technological University of Paraná, Campus Pato Branco, using visual inspection, photographic records and bibliographical research. This survey indicated cracks as the predominant defect, with six different shapes and accounting for 88.5% of the total number of registered anomalies. This was followed by the appearance of stains, related to the presence of microorganisms and corrosion products, while a small number of disaggregation in concrete and mortar and peeling of paint were visualized. It was also observed that contact with moisture was a factor present in the regions that accumulated more defects, possibly exerting a contribution. Even so, the anomalies did not represent an accentuated degradation of the environments, however, maintenance and correction are welcome so that problems do not evolve and impair the performance and durability of the building, in addition to making recovery more expensive.
