Defining corrosion parameters from naturally corroded bars: the CORR-DATA database

The scientific community is currently making a great effort to define models and techniques to improve assessment procedures for corroded reinforced concrete structures. One fundamental key for the applicability of such procedures is the knowledge on corrosion patterns occurring in existing structures. This paper presents the preliminary results of the project “CORR-DATA database”, aimed at collecting homogeneous and comparable characteristics of corroding reinforcing bars from naturally corroded structures. The analysis carried out on the first batch of bars extracted from a beam subjected to chloride-induced corrosion are presented, focusing on the characteristics of the minimum residual cross-section and the calculated maximum-to-average attack ratio.
