Barriers to the Prediction of Service Life of Metallic Materials
Abstract The degradation of metallic materials in buildings and other structures is frequently attributable to electrochemical corrosion processes. In this paper, general problems of corrosion prediction are first considered and it is shown that information derived from accelerated exposure tests or from investigations of electrochemical properties of idealised systems is often an inadequate guide to the behaviour of metallic components in real corrosive environments. Specific cases involving the durability of steel reinforcing bars in concrete and the behaviour of zinc-coated steel components in buildings are then discussed. These examples are chosen because they illustrate the difficulties involved in predicting service lives of metals that are exposed to complex and often ill-characterised environments of the sorts that may be encountered in constructional applications.
