CONCRETE BEHAVIOR IN SEAWATER: BIBLIOGRAPHICAL REVIEW

CONPORTEMENT DU BETON A L'EAU DER MER. SYNTHESE BIBLIOGRAPHIQUE

The most important problems in the tidal range area: mechanical stresses, permeability, freezing and thawing are discussed. Using highly resistant structures, the choice of structural forms and using high quality concrete of low permeability and adequate workability is analyzed. Air-entraining agents should be used to entrain controlled amounts of air, improving resistance to frost damage. The water/cement ratio should be less than 0.45. Corrosion occurs in concrete sea structures, in the submerged zone, as well as the splash zone and atmospheric zone. The attack of cement by sulphates can be avoided by using Portland Cement with a tricalcium aluminate content of less than 8%. Corrosion of reinforcing steel by chlorides can be avoided, if cathodic protection is applied. As a general rule concrete marine structures are subjected to mechanical and physico-chemical stresses. It seems that the fatigue behavior for concrete structures in marine environment is not well known. Therefore, fatigue experiments appear to be of great interest in determining the future design of offshore concrete structures.
