CONCRETE IN THE OCEANS

Reinforced concrete is being applied to an increasing number of very important ocean structures and vessels. The assurance of high performance and long term durability requires a good and basic understanding of the various deteriorating processes which may occur. Some experiences are briefly presented on the use of reinforced concrete as a construction material in marine environments. chemical deterioration of concrete in seawater should not represent any problem provided high quality concrete is applied. Freezing and thawing can also be controlled by appropriate use of air-entraining admixtures. It is primarily corrosion of embedded steel which may affect the performance. Although experience indicate that concrete sea structures can remain serviceable with little or no maintenance for at least 40 to 50 years, all structures for which safety and performance play an important role should be periodically monitored for steel potentials and electrical resistivity along the concrete surface. Such measurements should be part of the regular surveying and maintenance program. /Author/
