Cathodic Protection on Steel Reinforced Concrete Marine Structures

The use of cathodic protection has become the preferred method for mitigating corrosion of steel reinforcement in concrete. A wide variety of both impressed current and sacrificial systems have been effectively used to control the effects of corrosion.

The corrosion of reinforcing steel in concrete is considered the major cause of deteriortaion on steel reinforced concrete structures located in marine environments. Millions of dollars are spent every year in repairing the damaged structures to assure their safe use. This deterioration is most evident on substructure components - foundations footers pilings etc. - in southern climates. However the deterioration can also be present on superstructure components - bridge decks beams pile caps etc. on the Pacific coast or in northern states where deicing salts are commonly used. The use of cathodic protection has become the preferred method for mitigating corrosion of steel reinforcement in concrete on marine structures. A wide variety of both impressed current and sacrificial systems have been effectively used to control the effects of corrosion on steel reinforced concrete structures.This presentation will discuss:- Various types of marine structures and the industries thay are found in- Challenges of addressing corrosion damage to marine structures- Cathodic protection system solutions to protect structures and how they function- The best cathodic protection systems for particuler structure types.

Key words: corrosion, reinforcing steel, reinforced concrete, substructure, superstructure, deicing salts, cathodic protection, marine
