Abstract

This paper presents a simplified probabilistic approach to estimating the residual service life of concrete structural elements after repair. The repairs consist of replacing the concrete cover either partially or entirely with a cement-based repair material. In particular, the presence of a residual contamination in the remaining concrete layer and how the redistribution of the residual chlorides affects the determination of the service life are considered. Partial removal of the concrete cover may be appropriate for economic, execution-or construction-related reasons or also as a preventive measure etc. In such cases, it must be asked whether the remaining concrete layer has to be free from chlorides or to what extent it may still be contaminated with chlorides and how the residual contamination will affect the residual service life of the concrete structural element after repair (i.e. after the concrete cover has been partially removed and replaced with a repair material).
