    Abstract

    Cracking due to reinforcement corrosion defines an important limit state of durability and structural stability of concrete structures. By means of a comprehensive research work the influence of concrete porosity on the corrosion morphology and the mechanical behaviour of the concrete cover affected by the corrosion process could be investigated. The investigations allowed for the detailed analysis of the stresses, strains and the crack formation within the concrete cover. An analytical prediction model for concrete cover cracking was derived. This model enables the prediction of the time dependent damage process under conditions of practical relevance.
