Calibration Technique for Quantitative Chloride Measurements with µ-XRF in Cementitious Materials
Kaasa, Rannei Ida (Master thesis, 2018)Corrosion due to ingress of chlorides is one of the major deterioration mechanisms of reinforced concrete structures exposed to seawater or de-icing salts. The chlorides are transported through the porous cement paste in ... -
Comparison of the condition of steel fiber-reinforced shotcrete with water-glass and alkali-free activators after more than 20 years of service in a subsea road tunnel
Manquehual Mery, Cristobal Javier; Jakobsen, Pål Drevland; Holter, Karl Gunnar; De Weerdt, Klaartje; Danner, Tobias Alexander; Bruland, Amund (Peer reviewed; Journal article, 2022)The in-service condition of steel fiber-reinforced shotcrete installed more than 20 years ago as single-shell rock support lining in the Nordkapp subsea road tunnel was investigated. The novelty of this study is the ... -
Concluding destructive investigation of a nine-year-old marine-exposed cracked concrete panel
Geiker, Mette Rica; Robuschi, Samanta; Lundgren, Karin; Paraskevoulakos, Charilaos; Gundlach, Carsten; Danner, Tobias Alexander; Hjorth Jakobsen, Ulla; Michel, Alexander (Peer reviewed; Journal article, 2023)This study undertaken on a nine-year-old cracked concrete panel further investigates the impact of cracks on the corrosion performance of conventional steel reinforcement in marine-exposed concrete to explain observed ... -
Influence of cracks and spacers on chloride penetration and reinforcement corrosion in concrete
Strømme, Øyvind (Master thesis, 2017)This thesis studies the influence of cracks and spacers on chloride penetration and reinforcement corrosion in concrete. The study was conducted in connection with the Norwegian Public Road Authorities (NPRA) E39 project, ... -
Influence of Cracks on Chloride Ingress and Reinforcement Corrosion
Rygg, Andreas (Master thesis, 2017)Chloride induced reinforcement corrosion is a major durability problem in concrete constructions. It is consensus in literature that cracks facilitate chloride ingress, and may initiate early reinforcement corrosion. This ... -

Selvreparasjon og påvirkningen av riss på armeringens tilstand i opprisset betong - Undersøkelser av bjelker eksponert i marint miljø i 25 år
Moastuen, Ragnhild; Larsen Myklebust, Solveig (Master thesis, 2018)I dette prosjektet er det studert langtidsdata for tre bjelker som har stått eksponert marint i tidevannssonen i 25 år. Bjelkene har ulike betongresepter med ulikt innhold av bindemidler, henholdsvis 4,2 % silikastøv, 3,5 ...
