    • Al uptake in calcium silicate hydrate and the effect of alkali hydroxide 

      Yan, Yiru; Ma, Bin; Miron, G. Dan; Kulik, D.A.; Scrivener, Karen; Lothenbach, Barbara (Peer reviewed; Journal article, 2022)
      The effect of Al and of pH on the structure of calcium silicate hydrate (C-S-H), the most important hydration product in Portland and blended cement, was studied at Ca/Si ~1.0. The presence of Al led to higher amounts of ...

    • Effect of alkali hydroxide on calcium silicate hydrate (C-S-H) 

      Yan, Yiru; Yang, Shen-Yu; Miron, G. Dan; Colings, Ines E.; L'Hôpital, Emilie; Skibsted, Jorgen; Winnefeld, Frank; Scrivener, Karen; Lothenbach, Barbara (Peer reviewed; Journal article, 2022)
      This paper investigates the effect of KOH and NaOH on C-S-H structure and solubility. Both KOH and NaOH have a similar effect, they increase pH values and silicon concentrations, and decrease calcium concentrations. At ...

    • A long-term study on structural changes in calcium aluminate silicate hydrates 

      Barzgar, Sonya; Yan, Yiru; Tarik, Mohamed; Skibsted, Jorgen; Ludwig, Christian; Lothenbach, Barbara (Peer reviewed; Journal article, 2022)
      Production of blended cements in which Portland cement is combined with supplementary cementitious materials (SCM) is an effective strategy for reducing the CO2 emissions during cement manufacturing and achieving sustainable ...

    • Solubility and characterization of synthesized 11 Å Al-tobermorite 

      Lothenbach, Barbara; Jansen, Daniel; Yan, Yiru; Schreiner, J. (Peer reviewed; Journal article, 2022)
      The structure and solubility of hydrothermally prepared 11 Å Al-tobermorite with Al/(Al + Si) = 0.1 has been studied. NMR and FTIR data indicated the formation of a cross-linked, well crystalline 11 Å Al-tobermorite and ...
