Under the combined exposure of ocean environments and heavy structural loads there are a number of deteriorating processes taking place. However, it is not the disintegration of the concrete itself, but the electro-chemical corrosion of the reinforcing steel which represents the most critical and serious problem to the durability and safety of concrete sea structures. Observations indicate that detrimental amounts of chloride ions are capable of penetrating into high quality concrete beyond what would be a practical limit for the thickness of a concrete cover. Hence, for concrete structures in ocean environments it is necessary to look for preventative measures in addition to good, concrete cover. This is particularly important for prestressed concrete structures. In addition to taking preventative measures during design and construction,techniques should also be applied in order to periodically monitor the presence or absence of steel corrosion before it becomes too late.
