Designing concrete durability by coupling limit states of corrosion initiation and corrosion induced cracking of concrete cover

    Research output: Contribution to journalArticleScientificpeer-review

    Abstract

    The successful durability design of reinforced concrete structures
    requires models capable of reliably describing both mechanisms of
    damage and its progression over time. In a chloride laden
    environment, most models used typically disregard the actual
    damage, i.e. the corrosion of the reinforcing steel. Common service
    life design practice only considers the end of the initiation phase of
    the degradation process as a critical limit state. In this paper, a
    holistic approach is presented that couples models used for
    determining the time to depassivation and the time to cover cracking
    as a result of reinforcement corrosion in a single limit state
    calculation.
