Corrosion Theory

The corrosion of steel in concrete is a significant concern in infrastructure and construction industries. This chapter discusses the theories, processes, and effects associated with the corrosion of steel embedded in concrete structures. Understanding the major components of corrosion and the various corrosion types is crucial for comprehending the underlying mechanisms and developing effective corrosion management strategies. Corrosion theories, including corrosion thermodynamics and corrosion kinetics, provide insights into the fundamental principles governing the corrosion process. By examining the corrosion rate, influenced by factors such as potential electrode and environmental conditions, the severity of corrosion can be assessed. The detrimental effects of corrosion on steel in concrete, such as structural deterioration and loss of functionality, highlight the importance of implementing robust corrosion risk management practices. Thus, proper corrosion risk management techniques are essential for preserving the integrity, durability, and service life of concrete structures. This chapter lays the foundation for a comprehensive exploration of the corrosion of steel in concrete, examining its theories, processes, effects, and the strategies employed in corrosion risk management. By addressing the challenges posed by corrosion, stakeholders in the construction industry can ensure the longevity and safety of concrete structures.
