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 ... -
Durability of cracked SFRC exposed to wet-dry cycles of chlorides and carbon dioxide – Multiscale deterioration phenomena
Marcos-Meson, Victor; Geiker, Mette Rica; Fischer, Gregor; Solgaard, Anders; Jakobsen, Ulla Hjorth; Danner, Tobias; Edvardsen, Carola; Skovhus, T.L.; Michel, Alexander (Peer reviewed; Journal article, 2020)This paper describes an experimental study that comprised the exposure of cracked SFRC members to wet-dry cycles involving chloride and carbon-dioxide for two years. Results indicate that corrosion of steel fibres occurs ... -
Mineralogical Sequence of Self-Healing Products in Cracked Marine Concrete
Danner, Tobias; Jakobsen, Ulla Hjorth; Geiker, Mette Rica (Journal article; Peer reviewed, 2019)Self-healing of cracked concrete beams after 25 years of marine exposure was investigated. The extent of self-healing and the chemical and mineralogical composition of the self-healing products were characterized, and ...
