Parametric studies and application of a practical model for corrosion of galvanized steel in soil

The ability to influence decision at the design stage is one of the main advantages that corrosion prediction has over corrosion monitoring and proper design mitigation for corrosion, and the economical burden associated with them. In this work, a previously developed model for the corrosion rate of galvanized steel in soil at three different stages of corrosion, which considers the key soil corrosion parameters, is briefly introduced, some parametric and validation case studies are performed, and a few examples of some important applications are provided. Some modifications were also applied on the numerical model to extend the application of the models by including the effect of environmental conditions on the corrosion rate of galvanized steel in the soil. The improved model is an easy-to-use and flexible tool that can accurately estimate corrosion damage evolution of galvanized steel in the soil.
