25 years of field exposure of pre-cracked concrete beams; combined impact of spacers and cracks on reinforcement corrosion
Geiker, Mette Rica; Danner, Tobias; Michel, Alexander; Belda Revert, Andres; Linderoth, Oskar; Hornbostel, Karla (Peer reviewed; Journal article, 2021)The state of corrosion of three pre-cracked concrete beams was investigated after 25 years of marine exposure (atmospheric, tidal and submerged). The influence of inadequate plastic spacers was found to overrule the possible ... -
Durability aspects of cracks in concrete: field observations
Geiker, Mette Rica; Danner, Tobias; Hornbostel, Karla; Michel, Alexander (Nordic Concrete Research;17, Chapter, 2019)The research presented in this paper briefly summarises findings from a project on impact of cracks on reinforcement corrosion within the Norwegian Public Roads Administration’s R&D program “Ferry-free coastal route E39”. ... -
Non-destructive Test Methods for Corrosion Detection in Reinforced Concrete Structures
Hornbostel, Karla; Danner, Tobias; Geiker, Mette Rica (Peer reviewed; Journal article, 2020)Several inspection methods can be used to assess the corrosion state of steel reinforcement in concrete. Especially for periodical field surveys and monitoring, non-destructive testing (NDT) methods are to be preferred as ... -
Self-healing and Chloride Ingress in Cracked Cathodically Protected Concrete Exposed to Marine Environment for 33 Years
Danner, Tobias; Hornbostel, Karla; Strømme, Øyvind; Geiker, Mette Rica (NTNU report;R-1-2019, Research report, 2019-11-22)Cracks facilitate ingress of aggressive substances. Depending on the exposure, this might lead to early reinforcement corrosion initiation. Possible self-healing of cracks may reduce their long-term impact, and conditions ...
