OLGUIN COCA, F.J. et al. Influence of Environmental and Electrochemical Factors in the Durability of Concrete. Port. Electrochim. Acta [online]. 2004, vol.22, n.4, pp.321-334. ISSN 0872-1904.

This work is part of the DURACON project, in which it is characterized the concretes exposed durability in the present iberoamerican environmental conditions, being based in the exhibition of armed specimens in at least two different atmospheres, a marine and an urban, in each iberoamerican participant country. The results obtained by exposing these armed concrete specimens to the environmental conditions of the city Chihuahua, Mexico, during the first 15 months of exhibition, will be discussed in this work. Two concretes were designed, one with a relationship w/c (water/cement) = 0.65, and the other one with w/c = 0.45, and three cover thickness (1.5, 2.0 and 3.0 cm). Tests were mainly based in measuring electrochemical parameters that allowed evaluating the corrosion kinetics of the bars, by means of potential corrosion measurements and implementing the technique of linear resistance polarization in order to determine the corrosion rate. All this information will permit, with the use of specific models, to design durable concrete structures, and to repair appropriately those already existent, what will rebound in a decrease of the economic losses that at the moment is causing the phenomenon of corrosion in our country.
