    • Dolomite calcined clay composite cement - hydration and durability 

      Machner, Alisa Lydia (Doctoral theses at NTNU;2018:39, Doctoral thesis, 2018)
      Considerable amounts of CO2 are emitted during the production of cement. One way to reduce these CO2 emissions is to replace some of the cement clinker with supplementary cementitious materials (SCMs). A cement containing ...

    • Hydration of Composite Cements Containing Novel SCMs 

      Zuschlag, Pamela; Machner, Alisa Lydia; Hemstad, Petter; Kjellsen, Knut Ose; Zajac, Maciej; Ben Haha, Mohsen; Danner, Tobias Alexander; Justnes, Harald; Weerdt, Klaartje de; Geiker, Mette Rica (Peer reviewed; Journal article, 2024)
      The impact of novel supplementary cementitious materials (SCMs) on the phase assemblage and the pore structure in cement pastes was studied and linked to their impact on the compressive strength in mortar. The composite ...

    • The impact of curing temperatures on Portland composite cements – hydrate assemblage, porosity, and compressive strength 

      Zuschlag, Pamela (Doctoral theses at NTNU;2022:374, Doctoral thesis, 2022)
      Cement production stands for approx. 8% of the man-made CO2 emissions. One of the most common ways to reduce CO2 emissions in cement production is by replacing part of the clinker with supplementary cementitious materials ...

    • 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 ...
