Manifestações patológicas em estruturas de concreto armado: Estudo de caso em Santa Maria-RS

Abstract

Reinforced Concrete is a broad and widely used construction system, therefore, for the area of civil construction it is of paramount importance to know its behavior in all possible situations. Pathologies in reinforced concrete structures is a very broad topic and the knowledge of its possible causes and consequences is a necessity and motivation for professionals and researchers in the area to search for solutions. The main question is to know how to differentiate whether the pathologies can affect the structure in part or whether the pathologies will generate a serious structural shock. It is also of paramount importance to indicate correct and useful methods for the recovery of such pathological manifestation, for which the analysis must be carried out by a specialized professional. The present work was based on a literature review to understand the behavior of reinforced concrete and, mainly, to understand how pathologies arise as well as what are their main recoveries. After a theoretical review, the knowledge could be better understood through a case study, where several pathologies were seen in the reinforced concrete structure, among them we can mention the reinforcement that is exposed in the slabs, beams and columns, concreting failures, cover breaks, detored teeth. In the case study, some recovery methods were adopted, including injections, cuts, repairs with mortars, application of coatings, etc.
