Estudo de caso de avaliação em revestimento de fachada aplicado em habitação de interesse social no centro-norte do Paraná

Abstract

For the execution of a building, several steps are necessary, such as the mortar coating, which is intended to protect and finish. In the present day, the constructions have become very fast and several technologies had to be attached to civil construction, for the execution of coatings, the use of stabilized mortar was implemented, which brings several advantages and disadvantages to the buildings. Aiming to guarantee a quality, the present study aimed to evaluate the pathological manifestations in houses of social interest in the north center of Paraná, using characterization assay and tensile strength tests. In order to determine the causes of the manifestations, all stages of execution, construction method, materials employed, climatic conditions were monitored. In the survey of pathologies, 34 housing units were analyzed, where at least one of the facades of the house presented some pathology, with the mapping fissure being the most common, where 64.6% of the facades had the pathology. For the tensile strength assay, the results obtained were satisfactory before the standard, showing that the coating fulfilled its function, with the characterization test the results obtained also satisfied the values of the norm, but the parameters indicated by the laboratory, presented results that would not be ideal, so some pathologies may have their origin tied to these results. To solve these problems, several solutions were proposed and tested in order to solve and avoid new cases of manifestations. So, we can see the importance of conducting tests and controls to ensure the ideal quality for the coating to perform its function.
