Análise de manifestações patológicas em estrutura de concreto armado das instalações de uma fábrica de tecidos em Minas Gerais

Abstract

The construction industry has experienced a major expansion in recent years. However, it resulted in some aggravating factors such as adaptations to deliver the largest number of works with less rigor in quality control of materials and services performed, due to the short deadline for execution. Among other factors, such as lack of maintenance in buildings, have culminated in an avalanche of pathological manifestations, which can compromise the work in its structural, aesthetic and durability aspects. Pathological manifestations in reinforced concrete structures appear for several reasons cited throughout the report. This study aims to present the diagnoses carried out in a building, and the techniques for treatment and recovery. To this end, a bibliographical review was carried out on the subject, searching for the most varied authors and researchers in this area. To emphasize the research, a case study of a commercial building was presented. With these studies we can emphasize the different levels of pathologies found in constructions and their consequences as well as procedures that can minimize or eliminate some pathologies. In other words, the emergence and evolution of most of the pathological manifestations identified are related to maintenance and use failures that contribute to the early deterioration of structures, interfering with the fulfillment of use requirements, such as structural safety, functionality and durability.
