Carbonation resistance of concrete and mortar containing novel low clinker cement
Bjørndal, Marie Helene (Student paper, others, 2019)Corrosion of reinforcement steel is a major deterioration mechanism for reinforced concrete structures. Corrosion can be caused by the carbonation of concrete. In this report we test the carbonation resistance of a novel ... -
Effect of leaching on the composition of hydration phases during chloride exposure of mortar
Machner, Alisa; Bjørndal, Marie Helene; Justnes, Harald; Hanžič, Lucija; Šajna, Aljoša; Gu, Yushan; Benoît, Bary; Ben Haha, Mohsen; Geiker, Mette Rica; De Weerdt, Klaartje (Peer reviewed; Journal article, 2022)Mortar specimens were exposed to either a 3% NaCl solution or a 3% NaCl+KOH solution for up to 180 days. Exposure to the NaCl solution provoked much more leaching than the NaCl+KOH exposure. Leaching strongly impacted the ... -
Experimental carbonation study for a durability assessment of novel cementitious materials
Hanžič, Lucija; Robič, Sebastijan; Machner, Alisa; Bjørndal, Marie Helene; De Weerdt, Klaartje; Gu, Yushan; Bary, Benoît; Carreras, Rosa Maria Lample; Šajna, Aljoša (Peer reviewed; Journal article, 2021)Durability predictions of concrete structures are derived from experience-based requirements and descriptive exposure classes. To support durability predictions, a numerical model related to the carbonation resistance of ... -
Impact of leaching on chloride ingress profiles in concrete
Bjørndal, Marie Helene (Master thesis, 2019)Kloridinitiert armeringskorrosjon er en av hovednedbrytningsmekanismene for armerte betongkonstruksjoner. Klorider trenger igjennom betongoverdekningen over tid og forårsaker korrosjon når de når et kritisk kloridinnhold ... -
Impact of leaching on chloride ingress profiles in concrete
Machner, Alisa Lydia; Bjørndal, Marie Helene; Šajna, Aljoša; Mikanovic, Nikola; De Weerdt, Klaartje (Peer reviewed; Journal article, 2022)To investigate the effect of leaching on chloride ingress profiles in concrete and mortar, we exposed concrete and mortar specimens for 90 and 180 days to two different exposure solutions: 3% NaCl, and 3% NaCl with KOH ...
