Corrosion of Steel in Concrete: Prevention, Diagnosis, Repair

Provides an extensive, systematic guide for engineers to understand and combat the deterioration of reinforced concrete structures, particularly due to rebar corrosion. The content covers the fundamentals of concrete composition and its protective alkalinity, contrasting this with the reality that structures are not "eternal" because of corrosion initiation caused by carbonation and chloride penetration. Much of the text discusses the mechanisms and kinetics of corrosion, detailing the roles of water, porosity, and transport processes like diffusion and migration, and explores various preventative measures including quality control, special cements, corrosion-resistant rebar, and surface treatments. Finally, the source addresses inspection and condition assessment techniques, such as potential mapping and corrosion rate measurement, and outlines repair and rehabilitation strategies using conventional patching, as well as advanced electrochemical methods like cathodic protection and chloride extraction.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/civil_engineering_made_simpleProduced by:https://www.podcaistudio.com/
