CATHODIC PROTECTION OF CORRODED REINFORCED CONCRETE STRUCTURE

Abstract

The issue of corrosion in reinforced concrete buildings was first noted in the 1960s, and its prevalence has increased significantly since 1975. Corrosion poses a significant challenge in maintaining infrastructure, as it causes damage, deterioration, and even destruction of concrete structures. If left unchecked, severe corrosion can lead to unexpected failures and costly repairs, Since the introduction of cathodic protection systems in the 1970s, there have been significant advancements in system components and testing methods. Nowadays, various techniques are available to assess the extent and speed of corrosion, as well as the effectiveness of cathodic protection systems. While it is widely acknowledged that cathodic protection helps mitigate the corrosion of reinforcing steel in concrete, the exact impact of electric current passing through the concrete is not yet fully understood. Currently, there is a need to strike a balance between the complexities of concrete and cathodic protection, in order to develop a simple and functional cathodic protection system, The use of cathodic protection (CP) addresses the electrochemical nature of corrosion and provides corrosion protection. The study will provides the design and details of the installation techniques of a cathodic protection system applied to a structure with corroded steel.
