In a sacrificial anode system, a more reactive metal, such as zinc or magnesium, is connected to the steel rebars, sacrificing itself and preventing corrosion. In an impressed current system, an external power source is used to provide a protective current to the rebars, preventing corrosion. 5. Corrosion Inhibitors: Corrosion inhibitors are chemicals added to the concrete mix or applied as a surface treatment to the rebars. These inhibitors form a protective film on the rebars' surface, preventing corrosion by blocking the access of corrosive agents. 6. Stainless Steel Rebars: Using stainless steel rebars is an effective corrosion protection method. Stainless steel has a high resistance to corrosion, making it suitable for structures exposed to aggressive environments. It is important to note that the selection of the appropriate corrosion protection method depends on various factors, including the environmental conditions, expected service life of the structure, and cost considerations. Additionally, regular inspection and maintenance of the corrosion protection system are essential to ensure its effectiveness over time.
