Z7-05 Durability Modelling Reinforcement Corrosion in Concrete Structures

The key objectives of this Recommended Practice are to review commonly used models for prediction of reinforcement corrosion in concrete structures and input parameters for chloride diffusion, carbonation resistance and corrosion of reinforcement (including stressed tendons) and to determine the most suitable models and input parameters with relevant statistical distributions.

This Recommended Practice is intended to provide Reinforcement Corrosion specialists with recommended modelling processes and inputs to ensure that a consistent and reliable approach is followed. This Recommended Practice will inform designers, asset owners, contractors and the wider industry about the benefits and limitations of commonly used models. It will ensure that modelling is undertaken with appropriate resources and the outputs adopted appropriately, whether in the overall design of new structures or in asset management and maintenance plans for existing structures. It includes materials selection and intervention options for specific design and residual service lives.
