Several proposals can be found on prediction of the time to reinforcement corrosion and service life duration. In present communication a proposals is made on using the electrical resistivity to calculate both the initiation and propagation periods. For the time to corrosion onset, the electrical resistivity represents the porosity and its connectivity and therefore can be used to model transport processes. Due to the reaction of chlorides and carbon dioxide with cement phases, the resistivity has to be factorised by a “reaction factor” accounting for it. Concerning the propagation period, the electrical resistivity is an indication of the moisture content of concrete and therefore, it has a certain relationship with the corrosion cement. | Descripción: | Trabajo presentado en el 10th DBMC - International Conference on Durability of Building Materials and Components, celebrada en Lyon (Francia), del 17 al 20 de abril de 2005 | URI: | http://hdl.handle.net/10261/229587 |
