Application of marine field data for prediction of chloride ingress in concrete
Fjendbo, Simon (Doctoral theses at NTNU;2022:173, Doctoral thesis, 2022)A fixed link is about to be built across the Fehmarn Belt between Denmark and Germany. The main structure of the link is a submerged reinforced concrete tunnel with a design service life of 120 years considering corrosion ... -
Correlating the development of chloride profiles and microstructural changes in marine concrete up to ten years
Fjendbo, Simon; Fjendbo, Simon; Sørensen, Henrik E.; De Weerdt, Klaartje; Jakobsen, Ulla Hjorth; Geiker, Mette Rica (Peer reviewed; Journal article, 2022)After ten years of marine exposure, chloride and calcium profiles and petrographic data were obtained from the tidal and submerged zones of six concrete panels differing in binder composition. Moisture and portlandite ... -
Estimation of chloride threshold values by use of the square root method and anode ladders
Rygh, Jan-Morten Strømseth (Master thesis, 2021)Abstract will be available on 2023-06-29 -
The square root method for chloride ingress prediction - Applicability and limitations
Fjendbo, Simon; Sørensen, Henrik E.; De Weerdt, Klaartje; Geiker, Mette Rica (Peer reviewed; Journal article, 2021)A recent observation showed a square root time dependency of the ingress depth of a fixed (reference) chloride concentration of 0.05% chloride by mass of concrete for submerged exposure in Kattegat and the Baltic Sea. The ... -
When and How Should Chloride Profiles be Calibrated for Paste Fraction?
Fjendbo, Simon; De Weerdt, Klaartje; Sørensen, Henrik E.; Geiker, Mette Rica (Peer reviewed; Journal article, 2022)Due to stochastic and systematic variations in the paste fraction, data for total chloride content are occasionally calibrated using parallelly measured calcium content as a measure of the actual paste fraction − assuming ...
