Resumo:
Corrosion is the most recurrent pathology in reinforced concrete, responsible for high costs in the recovery of affected structures. In addition to direct costs such as materials used in the recovery, specialized labor, replacement of affected parts or equipment, there are indirect costs such as the interruption of use of the structure, mobilization of residents in case of residential buildings, loss of production in case of industrial buildings, among others. Finding and introducing means to combat and prevent corrosion is extremely important. Cathodic protection has been presented in the last decades as an effective way to combat the corrosion, as it not only paralyzes the corrosive process completely, but also preventing the combat to new points. Its use has been increasingly applied in structures such as bridges, industrial and residential buildings, and tunnels. Various materials have been tested and approved, adaptation system for flexibility and adaptation to better each structure. Case reports with the use of cathodic protection have had attention even after years of installation. This dissertation presents cathodic protection, its systems of use, cases in which it was installed, an experiment with cathodic protection by impressed current for the restoration of a steel tool, as well as a computational model developed for the design of galvanic anodes for reinforced concrete structures.
