Advancements in Galvanic Protection for Marine Structures
Publication: Ports 2022
ABSTRACT
Concrete structures exposed to a marine environment can experience high maintenance costs and reduced service life due to corrosion. This is particularly true for concrete reinforced piles in seawater (or brackish water) where an individual concrete pile can have a variety of exposure conditions, including airborne chlorides, periodic wetting by splashing, regular wetting by tidal activity, and fully submerged. Galvanic jacketing systems have been successfully employed to address active corrosion on concrete piles in all exposure conditions. There are different variations of galvanic systems that incorporate zinc-based embedded anodes, stay-in-place forms, and submerged bulk zinc anodes. Selecting the best galvanic jacket for the application will help to address corrosion-induced deterioration and will preserve and extend the service life of concrete piles in the marine environment.
