Title: Recommendations for increased durability and service life of marine concrete infrastructure

In many countries, deterioration and repair of important marine concrete infrastructure has emerged as a most severe and demanding challenge for the owners of structures. Although a number of deteriorating processes may represent potential problems, extensive experience demonstrates that electrochemical corrosion of the embedded steel poses the most critical and greatest threat to the durability and long-term performance of the structures. Although current standards have been improved in recent years, still an uncontrolled penetration of salt with subsequent steel corrosion can take place on relatively new important marine concrete structures. As soon as the corrosion starts, the owner has a problem, which in the beginning only represents a cost problem but later on also develops into a more difficult safety problem.
