Avaliação das manifestações patológicas nos blocos 1, 2 & 3 da unidade 2, Unifesspa, Marabá-Pa

Abstract

This work discusses the theme of the construction pathologies, seeking to analyze the pathological phenomena observed in three specific buildings of Unit 2, on the Campus of the Federal University of South and southeast of Pará in Marabá. The study aims to analyze the problems encountered, identifying the causes of its origin and proposing appropriate solutions to its repair. The work was developed based on the bibliographic research, in loco inspections, in the comparison of pathologies found with those presented by the authors used as reference and, in the laboratory analysis of the behavior of concrete (through Manufacturing of specimens). The bibliographic research was developed prioritizing the use of current references (2008-2019) that have been published in journals (national or international). In loco inspections were made on four dates, and in each one were made photographic records of the pathologies found. The results obtained were constructed through the analysis, in the first instance, of the comparison between the pathologies found and what was presented in the bibliography, added to this, laboratory tests were developed to provide a more Solid in the search for the best possible solutions. During the laboratory phase, the concrete characteristics were observed through destructive assays (compression and axial compression) and non-destructive tests (capillarity, exsudation, permeability and others). The results obtained in the tests, together with what was found in the bibliography, made it possible to identify the most appropriate solution for each problem studied. Finally, with this work, it was sought that the pathologies found were better understood and, thus, could propose to the sector responsible for maintaining the buildings the most effective solutions for their treatment.
