Corrosion and its Consequences for Reinforced Concrete Structures

This book serves as an indispensable guide for engineers, scientists and researchers, exploring the fundamental aspects of corrosion in reinforced concrete. Its originality lies in the coupling between the reinforcement corrosion of reinforced concrete and its mechanical behavior.The authors describe the specific theoretical foundations of the corrosion of steel in concrete and its interactions with the structural aspects, including service cracking and defects in the placement of concrete.

The book contains a study of the mechanisms of degradation of the mechanical behavior of reinforcements and the reinforced concrete composite, such as reduction of ductility, bearing capacity, redistribution of efforts by formation of plastic hinges and increase in the beam deflection in service. A diagnostic method based on corrosion-induced crack detection is presented in the book, and then paired with a recalculation method which allows us to predict the different aspects of the residual mechanical behavior. Several end-of-life ELS and ELU criteria are described, and the authors propose an approach to estimate the residual lifetime. Finally, the book presents the cathodic protection that allows the progression of corrosion to be contained within the corroded structures.

As well as academics, this book is aimed at civil engineers who are faced with the issue of corrosion in aging structures.
