Resumen

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.

Palabras clave

Corrosión, Escoria activada alcalinamente, Carbonatación, Espectometría Mössbauer.
