The reuse of reinforced concrete elements requires a fast but effective characterisation and assessment. As this would be inefficient using standard destructive methods, developing, validating and analysing a targeted set of in-situ and non-destructive testing methods including application and automatisation strategies is a core objective of sub-project B02. The second objective is the element classification from the point of view of durability and remain-ing service life. This is achieved by ranking the elements into resistance classes under predefined reuse scenarios based on the concrete properties, remaining protective concrete cover and inherent degradation.
