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.
