CORROSION OF REINFORCING STEEL IN CONCRETE STRUCTURES SUBMERGED IN SEAWATER

For an under-sea tunnel project, laboratory and field tests have been carried out to study the influence of permanent submersion in re-circulating seawater on the corrosion of steel in reinforced concrete. For each concrete mixture, cube specimens of plain concrete and beams of reinforced concrete were made. Sound as well as pre-cracked beams with a crack width of about 0.03, 0.3 and 1.0 mm were produced. The following parameters were measured as a function of time: chloride penetration as well as electrical resistivity in plain concrete specimens, and the corrosion rate of steel in reinforced concrete beams by visual and microscopic examinations.
