    • Chloride binding in Portland composite cements containing metakaolin and silica fume 

      Babaahmadi, Arezou; Machner, Alisa; Kunther, Wolfgang; Figueira, João; Hemstad, Petter; De Weerdt, Klaartje (Peer reviewed; Journal article, 2022)
      This paper investigates how the composition of Portland composite cements affects their chloride-binding properties. Hydrated cement pastes prepared with a reference Portland cement and composite Portland cements containing ...

    • Impact of electrodialytic remediation of MSWI fly ash on hydration and mechanical properties of blends with Portland cement 

      Ebert, Benjamin A. R.; Geiker, Mette Rica; Kunther, Wolfgang; Kirkelund, Gunvor M. (Peer reviewed; Journal article, 2021)
      Municipal solid waste incineration (MSWI) residues such as fly ash and air pollution control (APC) residues may serve as new supplementary cementitious materials (SCM). These SCMs may, however, require a pre-treatment to ...

    • Microstructural changes and mass transport in cement-based materials: a modeling approach 

      Michel, Alexander; Marcos-Meson, Victor; Kunther, Wolfgang; Geiker, Mette Rica (Peer reviewed; Journal article, 2021)
      A generic modeling framework is presented to relate microstructural changes, i.e. changes in the pore volume distribution and phase assemblage, and mass transport in cement-based materials. The modeling framework accounts ...

    • Phase changes in cementitious materials exposed to saline solutions 

      Weerdt, Klaartje de; Bernard, Ellina; Kunther, Wolfgang; Pedersen, Malene Thostrup; Lothenbach, Barbara (Peer reviewed; Journal article, 2023)
      This article summarizes long-term degradation mechanisms of cementitious materials in contact with fresh and saline solutions based on a review of experimental observations in field and laboratory studies. In addition, a ...

    • Sulfate resistance of calcined clay – Limestone – Portland cements 

      Shi, Zhenguo; Ferreiro, Sergio; Lothenbach, Barbara; Geiker, Mette Rica; Kunther, Wolfgang; Kaufmann, Josef; Herforth, Duncan; Skibsted, Jørgen (Journal article; Peer reviewed, 2019)
      Calcined clays emerge as a promising source of supplementary cementitious material, which can provide a significant lowering of the Portland clinker content in blended cements. This study focusses on sulfate resistance of ...
