Prediction of Carbonation and Chloride Ingress in Cracked Concrete Structures
Original language description
Carbonation and chloride ingress are the most relevant damaging mechanisms for steel corrosion in reinforced concrete structures. Massive utilization of supplementary cementitious materials in cement binders implies recalibration of existing models for these phenomena. The carbonation model formulated by Papadakis and the model for chloride ingress from Kwon are extended for crack effects, which accelerates both damaging mechanisms. Both models were reformulated in an incremental form, allowing a gradual crack growth. It was found that the crack width 0.3 mm decreases the induction time approximately five times when compared to uncracked concrete. Validation on in situ samples shows good predictions for chloride profiles.
