The Sacrificial Anode Cathodic Protection of Reinforced Concrete Structure in the Splash Zone

Corrosion of reinforced concrete structure in the marine environment is easily happened because of the influence of chloride ion, and the corrosion in the splash zone is the most serious. Cathode protection is the most common and effective way in anticorrosion method. For simple steel structure, anticorrosion technology has been basically mature^[1].But for some complex marine engineering structures, many key technologies have not been resolved, which constraints the design and construction of such facilities. In this paper, combined the experiments and the research of the model piles of the coal wharf of Rizhao Port, the sacrificial anode protection technology has been introduced and some problems have been solved, such as the relevant operation technologies, parameter design, material selection and so on.
