CORREA, Esteban A. et al. Atmospheric deterioration of concrete exposed in variable aggressiveness Colombian Scenarios. Ing. Desarro. [online]. 2008, n.23, pp.1-9. ISSN 0122-3461.

The concrete behavior in service depends on the atmospheric conditions where it is exposed. The determination of the atmosphere effect in stability of a given material depends on several factors related with time of wetness and atmospheric pollution. In Colombia, a few studies about this subject had been performed. In this study, cylindrical specimens of mortars, reinforced and non-reinforced, were exposed in Medellin, Bogota and Barranquilla. In order to establish the deterioration degree of mortars, after exposure, electrochemical and carbonation tests were carried out to the reinforced and non-reinforced specimens, respectively.

Keywords : Atmospheric Corrosion; concrete; carbonation; electrochemical test.
