Abstract: Onshore reinforced concrete structures are vulnerable to deterioration due to carbonation.
Condition assessment is a vital task, which helps to determine the reliability of structural
elements over the remaining service life. This study assesses the condition of reinforced
concrete structural elements (i.e. consoles) which are 53 years into their service life. The
reinforced concrete consoles, exhibiting no visible signs of corrosion, were chosen to measure
carbonation depths. In addition, non-destructive testing method: half-cell potential
measurements were taken over the surfaces of the consoles. A full-probabilistic service life
prediction model was used to calculate the expected service life, and a comparison was made
based on the actual carbonation depth measurements.
