Análise de manifestações patológicas no reservatório da Estação de Tratamento de Água – ETA, do município de Olho D’Água do Casado (AL)

Abstract

The present study analyzes the existence of concrete pathologies in a reservoir of the Water Treatment Station (ETA) in the municipality of Olho D'Água do Casado (AL) the theme is of relevance due to the public use of the reservoir and the choice of the constructive material in question, the reinforced concrete. Over time and the development of studies on building materials, it was observed that reinforced concrete is one of the building forms that bring the most benefits in terms of usability and resistance. However, like all concrete structures, the study observed that the reservoir in question could present several known pathologies. The general objective, therefore, included the investigation of the reservoir, its general characteristics and the development of pathologies. As specific objectives, we sought to understand the dynamics of pathologies, their analysis process from an academic perspective, classification and proposition of solutions, according to what the specialized literature recommends, as well as the Brazilian Technical Standards (NBR). The methodology comprised the mixed research: field and bibliography. For the field research, technical visits to the reservoir in question (surveys) were interpolated with the use of equipment, in order to carry out non-destructive tests and photographic records. In the documentary part, the history of the building was investigated, which allowed for a measurement of the damage and the relationship between the time of existence and the quality of the construction material; A bibliographical review was also elaborated on the theme presented and the main aspects involving concrete pathologies. The research found a significant number of pathologies present in the reservoir, which, given its frequency of use and its characteristics, demand immediate intervention, since it is possible that there are damages in the medium term, compromising the useful life of the reservoir, compromising both its performance and the quality of the water supplied to the community.
