Reflects on the progress that has been made in the past 20 years regarding knowledge of steel corrosion in concrete and the disparity between the current level of understanding and practice. Two examples are taken from common practice: the measurement of the chloride ion content of concrete and the measurement of half-cell potentials, to illustrate the implications of a lack of understanding of basic principles. Paper concludes with an identification of the research needed to provide a more complete understanding of the mechanism and the factors influencing the corrosion of steel embedded in concrete.
