Abstract


Interpretation of chlorides profiles is important to predict concrete structures service life, among other factors. However, reported results are, in general, from small specimens exposed to specific atmospheres instead of real structures. The objective of this work was the obtention and interpretation of the chlorides profiles forms from several bridges of the Turiguanó-Coco Key viaduct in Cuba. The results verified data from other authors but on different structural elements and similar atmospheres. The form of the chloride profile for structures similar to those in the viaduct bridges, exposed to tropical marine atmosphere, is consistent and changes in intensity with the winds direction and the blocking to them by parts of the structure. The possible effect of the wet and drying process is also discussed.
