Corrosion monitoring at submerged concrete structures - macrocell corrosion due to contact with aerated area
Since about 1980 Corrosion Monitoring Systems have been used in several concrete structures in aggressive environment world-wide. Most of these systems are based on the Ladder-type sensor consisting of 4 or 6 pieces of steel positioned at different depths below the concrete surface. While the systems work properly in usual outdoor environment, some questions have arisen for submerged conditions, e.g. outer sides of tunnels, piers in sea water or foundations in wet soil. These questions include the problem of macro-cell formation between reinforcement in submerged concrete and in neighboured aerated concrete, which might lead to severe corrosion problems under certain configurations of structures. To gather the existing information and knowledge within this field a task group within the European Federation of Corrosion EFC, Working Party 11 dealing with corrosion in concrete has been established. This paper summarises the results from the first meeting in Copenhagen on 23 and 24.of May 2007.
