structures is little used, although it is the most adequate to preserve
and guarantee the longevity of the structures. It is used, after
presentation of the causes, the corrective maintenance. The present
research carried out a study through bibliographical reviews and
publications on the main causes of pathological manifestations and the
corrosion of the reinforcements in reinforced concrete. Thus, the
objective of this investigation is to analyze the main factors that
influence the corrosive process and the origin of the main agents that
cause the partial or total loss, compromising the durability and useful
life of the reinforced concrete structures. The methodology presents the
types of pathologies more frequent, approach the main causes
highlighting the importance of avoiding corrective maintenance. It is
concluded with this study that the main pathologies in the reinforced
concrete were the corrosion of the reinforcement, the leaching of the
concrete causing the carbonation, which is the main cause of the steel
slaking of the hardened concrete, the lack of periodic maintenance of the structures and the insufficient coverage due to poor performance of
services. | | Keywords : | | | Carbonation. Leaching. Acidrain. Porosity. Acids. |
