| description | In this paper is presented the application of the galvanostatic pulse measurement which occurs in the activated slag concrete, submitted to accelerated carbonation processes. As reference material, we used ordinary Portland cement. Using the galvanostatic pulse technique enabled us the resistances values calculation which were involved separately in the carbonation process, allowing to find the corrosion rate by the Stern and Geary equation. The corrosion products were determined by the technique of Mössbauer Spectroscopy, corresponding to magnetite, goethite and wuestite. |

Presenta la aplicación de la técnica de pulsos galvanostáticos en el concreto de escoria activada alcalinamente, sometido a procesos acelerados de carbonatación. Como material de referencia se utilizó el concreto Portland ordinario. La utilización de dicha técnica permitió calcular el valor de las resistencias involucradas en el proceso de forma separada, permitiendo hallar la velocidad de corrosión mediante la ecuación de Stern y Geary. Los productos de corrosión fueron determinados con la técnica de Espectrometría Mössbauer, correspondientes a magnetita, wuestite y goethita.
