Abstract: Deterioration of reinforced concrete structures due to aggressive influences is serious problem
worldwide. It is recognized that corrosion of steel reinforcement in concrete is the major
reason for serious damages and degradation of RC structures. Proactive maintenance before
significant damage occurs to the structure optimizes cost and impact on the structure. To be
able to perform proactive maintenance of corroding structures, continuous corrosion
monitoring which is able to predict future deterioration is essential. The work presented was
focused on the analysis of measurement techniques for corrosion monitoring. Based on the
review of the existing test methods and criteria that methods must be non-expensive, relative
simple and capable to detect corrosion at early stage three techniques were selected for
additional analysis through experiments. Selected techniques are implementation of
multidepth sensors for macrocell currents, corrosion potential and electrical resistivity
measurements. A series of laboratory measurements and data evaluations, as well as
calibration of selected techniques and sensors were carried out.
