Confirmation of a Model to Predict Chloride Ion Penetration with Peak over Time

Abstract

This paper will discuss how previous research presented a model to forecast chloride ion penetration over time in samples where chloride profiles form a peak, i.e. the concentration of chloride ions first increases as we move from the surface to the interior of the structure and then show a decrease after a specific depth. This study presents the variation of this profile over time through measurements at different ages and compares these results with the values forecast by the model of the authors using the first profile measured in the structure. The model showed good accuracy in this case study and should be confirmed in other structures in use.
