CANADIANS EVALUATE BRIDGE CORROSION
The article describes a research project by the Institute for Research in Construction, National Research Council of Canada, to evaluate corrosion of the steel reinforcement in repaired concrete, for example in bridges. The project has shown that corrosion can be predicted more reliably when the results from various corrosion monitoring techniques are considered and analyzed. Several monitoring techniques, including half-cell potential, linear polarization, and concrete resistivity measurements, were used to evaluate the state of the steel reinforcement in repaired concrete from four slabs removed from the Perley Bridge in Hawkesbury, Ontario. The investigation clearly showed that each type of corrosion measurement has specific characteristics and limitations and that, in combination, the measurement techniques can provide a good indication of active corrosion in the reinforcement.
