Estudo das manifestações patológicas nas estruturas de concreto : análise das anomalias visuais em cinco estações de metrô de Belo Horizonte

Abstract

Pathological manifestations in concrete structures are still a much discussed topic and have been gaining importance in the construction sector in recent years. Many studies address the issue of pathologies, such as Sitter's law, which shows the gradual increase in repair costs when preventive maintenance measures are neglected, either by the government or by private assets. Thus, this work aims to analyze the visible pathological manifestations that affect reinforced concrete structures in 5 (five) stations of the 19 (nineteen) stations that make up the electric train lines (subway) in the city of Belo Horizonte. To this end, it sought to conceptualize, through the literature and current technical standards and through verifications and investigations in loco, to make a connection between the literature and the pathological manifestations verified during the study. The anomalies were, therefore, examined, their causes identified and their severity attributed, as well as the appropriate correction procedures to the notes.
