Abstract

This paper presents a comprehensive analysis of electrochemical chloride extraction (ECE) as a remediation technique for reinforced concrete structures suffering from chloride-induced corrosion. The study thoroughly examines the principles of ECE, emphasizing its role in reducing corrosion and extending the lifespan of concrete infrastructures. It explores various measurement methodologies to assess ECE's efficacy, focusing on outcomes like effective chloride removal, corrosion prevention, and pH changes in concrete. The review also highlights key factors influencing ECE's performance, including the types of electrodes and electrolytes used, and the impact of different environmental conditions. Particularly, the paper discusses potential disadvantages and risks associated with ECE and recommends using caution in its application. The conclusion of the study stresses the need for continued research to evaluate the long-term effectiveness and durability of ECE treatments, particularly in different environmental settings. This comprehensive analysis aims to contribute to the development of knowledge in the field of civil engineering, especially in the area of concrete durability and corrosion prevention. The article is a significant resource for researchers and professionals seeking to understand and apply ECE in concrete rehabilitation projects.
