Abstract:

Approach for the Assessment of Concrete Structures Subjected to Chloride Induced Deterioration

The maintenance of an adequate safety level of concrete bridges under their gradual degradation due to traffic and environmental actions during service life is an expensive, problematic and questionable task. Chloride ion ingress is an important aspect of durability design and maintenance, especially in regions where winter salt application for traffic safety is common, e. g. for highways. A feasible approach for the assessment of chloride induced deterioration and its consequences on the safety level, remaining service life and thus maintenance planning will be presented by a case study. Steps include the extraction of samples, laboratory test, inverse analysis and prognosis of chloride ingress, prediction of likely corrosion propagation over time and determination of the current and future safety level with regard to code based service limit states and ultimate limit states. Finally different maintenance strategies are compared with respect to the total life cycle costs.
