The development of this work consists in the assessment of the efficiency of
employment of recursive plots in the study of corrosion process of reinforced
steel embedded in concrete. The development of the recursive plots is given by
the statistical treatment executed to the Potential and Current time series
obtained as a result of the Electrochemical Noise technique (EN). The plots
derived time series of concrete cylinders built with and without the addition of
sodium chloride in the mixing water reveal patterns which indicate that under
the given exposure conditions it is possible to get information about the
mechanism of corrosive process this states some characteristics where the
heterogeneities of the concrete matrix come out, and that whit other analysis
methodologies would be hard to detect.
