Options for reducing the risk of reinforcement corrosion in R.C. structures and their incorporation into the design process Available to Purchase

The paper describes various options which enhance the durability of reinforced concrete by reducing the risk of reinforcement corrosion. These include different cementing systems, chemical admixtures and fibres, and surface treatments and coatings. Models for predicting the time to corrosion are described and the ways in which the different measures influence the critical input parameters are discussed. Durability design is also discussed, the limitations of the current deemed‐to‐satisfy approach are highlighted, and a new performance based method is proposed. Finally, a methodology is proposed for selecting the most cost‐effective options in relation to the required design life of the structure.
