CSIC ORCID | Fecha de publicación: | feb-1992 | Editor: | Elsevier BV | Citación: | Corrosion Science 33(2): 237-249 (1992) | Resumen: | The effects of macrocells formed between active (depassivated) and passive areas on the corrosion rate of steel reinforcements in concrete beams and slabs are studied. With a uniform distribution of current lines on the electrodes, the anodic current density (i.e. the corrosion rate) is a function of the difference in potential, ohmic resistance and polarization resistance. This case is approached when passive and active reinforcements are placed opposite each other. A coplanar location of the anode and cathode areas on the reinforcements results in a non-uniform distribution of the current. These cells are modelled by means of a transmission line circuit. A reasonable concordance is obtained between the theoretical predictions and the experimental data. | Versión del editor: | http://dx.doi.org/10.1016/0010-938X(92)90148-V | URI: | http://hdl.handle.net/10261/225454 | DOI: | 10.1016/0010-938X(92)90148-V | Identificadores: | doi: 10.1016/0010-938X(92)90148-V issn: 0010-938X |
