Incorporation of Concrete Rehabilitation Measures into Life-Cycle Maintenance

Key components of life cycle analysis of concrete structures are models for the assessment of the actual condition and for the prediction of its further development. Durability models have to consider the different influencing effects and degradation processes throughout the entire life cycle of a structure taking into account mutual dependencies, interactions, scattering and uncertainties. If reinforced concrete structures have been repaired during their lifetime, aging and deterioration of maintenance measures - like surface coating or concrete cover replacement - also must be taken into account. Degradation mechanisms of repair measures are different and they are going to be crucial for the durability of the repair measure. Taking into account the important parameters - like bond properties between concrete and repair mortar under thermal gradients, or of the adhesion influencing parameters of surface coatings - prediction models are needed. In this contribution, first ideas are presented on how the complex dependencies of the functionality and durability of repair measures may be recorded.
