By designing with corrosion prevention in mind and practicing through preventive maintenance, the overall service cost of a concrete structure can be substantially reduced. This book takes a probabilistic approach to the engineering design issues for controlling durability and service life of concrete structures in severe environments. It reviews field performance, deteriorating processes, and codes and practice; describes methods for calculation of corrosion probability; explains performance-based concrete quality control; discusses calculation of life cycle costs and life cycle assessment; and offers recommended job specifications.
