Abstract


This paper studies the corrosion rates of active and passive rebars embedded in concrete in various degrees of wetness using different electrochemical techniques. The ability of the electrochemical noise to quantificate the intensity of the attack and the advantages of this method are stressed. Data that prove that the corrosion rate is proportional to the current noise and independent to the potential noise in this system are also shown.
