Abstract
The protection of Egyptian reinforcing concrete infrastructures from corrosion is a pressing and critical task for construction engineering and industry, particularly in coastal locations. The primary aim of this case study is to integrate the advantages of both sacrificial anode cathodic protection (SACP) and impressed current cathodic protection (ICCP) in a single cathodic protection (CP) system and to use the new system in Alamein New Place near the Mediterranean sea (Egypt). The results showed that the new cathodic protection system is running very well to protect the concrete iron bars from corrosion. With the passage of time, the protective system’s efficiency and stability improve. During 30 days, the zinc anode’s potentials remain much more negative, indicating that the zinc anode can retain strong electrochemical activity for an extended length of time. The application of the CP method decreases the corrosion rate of rebar steel in concrete samples over time, according to electrochemical impedance spectroscopy (EIS).
