    • 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 

      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 ...
