The investigation of the moisture behaviour in concrete is crucial for assessing the corrosion risk of reinforcements. In the CRUFI and NAVE projects, literature review on corrosion in concrete was evaluated and various concrete specimens with different chloride contents were investigated and their hygrothermal properties and corrosion behaviour were analysed. Furthermore, a three-stage evaluation procedure for determining corrosion risk in concrete was created. Additionally, material-dependent corrosion maps were created to assess the long-term corrosion behaviour of steel.
Keywords: concrete, moisture distribution, liquid transport, transient corrosion prediction, chloride induced corrosion
