Fissuras no concreto armado: causas, consequências, formas de mitigação e reparos

Abstract

The present study aims to describe one of the main pathological manifestations presented in reinforced concrete structures, the cracks, with emphasis on their formation mechanisms, since the understanding of this phenomenon is of total importance for the orientation of decisions regarding the recovery of cracked components or the adoption of preventive measures, including the elabora-tion of projects with specifications, technological control of materials and service. These anomalies are the result of tensions in the components of the concrete structure, which can affect its aesthetics, functionality, durability and useful life of the building. They can also be caused by differential settlements, overloads, thermal and hygroscopic movements. Thus, the manifestation in concrete was evidenced in a general context, using illustrative tables of the causes of cracks and their consequences in reinforced concrete. Evidencing the forms of identification and repair that can be promoted from the presented anomalies, seeking to solve or mitigate them in a timely manner with the indicated prognoses.
