NIEVES MENDOZA, D. et al. Guard Ring and Electrochemical Noise Employment in the Evaluation of the Steel-Concrete System. Port. Electrochim. Acta [online]. 2004, vol.22, n.4, pp.305-320. ISSN 0872-1904.

To evaluate the electrochemical parameters of the reinforced concrete specimens at laboratory level there is no problem at all, because one can use any well-known electrochemical technique, but in site monitoring, there are few techniques being able to obtain these parameters. In this work a viable alternative is presented for the electrochemical evaluation of the reinforced concrete specimens in laboratory or in site monitoring. In order to have a reference of the corrosion rate obtained with the electrochemical noise technique and to be able to establish if these are real ones, measurements with commercial equipment were made applying the polarization resistance technique.

Keywords : corrosion; electrochemical noise; polarization resistance; armed concrete; monitoring.
