This paper intends to review the main systems of monitoring the degradation of reinforced concrete structures
with steel that have been patented in the last 10 years.
Given that the degradation process in the large majority of cases is an electrochemical corrosion process of the
reinforcement caused by chemical actions on the structure, the systems are generally systems that determine
The systems are essentially sets of electrodes with different arrays that allow the implementation of different
electrochemical techniques such as linear polarization resistance, electrochemical impedance spectroscopy,
electrochemical noise, ionic conductivity, in order to obtain information about reinforcement potentials and corrosion
rates and penetration speeds of aggressive agents.
