Friedel's salt profiles from thermogravimetric analysis and thermodynamic modelling of Portland cement-based mortars exposed to sodium chloride solution
Shi, Zhenguo; Geiker, Mette Rica; Lothenbach, Barbara; De Weerdt, Klaartje; Garzón, Sergio Ferreiro; Enemark-Rasmussen, Kasper; Skibsted, Jørgen (Journal article; Peer reviewed, 2017)Thermogravimetric analysis (TGA), powder X-ray diffraction (XRD) and thermodynamic modelling have been used to obtain Friedel's salt profiles for saturated mortar cylinders exposed to a 2.8 M NaCl solution. Comparison of ... -
Role of calcium on chloride binding in hydrated Portland cement–metakaolin–limestone blends
Shi, Zhenguo; Geiker, Mette Rica; De Weerdt, Klaartje; Østnor, Tone Anita; Lothenbach, Barbara; Winnefeld, Frank; Skibsted, Jørgen (Journal article; Peer reviewed, 2017)Chloride binding is investigated for Portland cement–metakaolin–limestone pastes exposed to CaCl2 and NaCl solutions. The phase assemblages and the amount of Friedel's salt are evaluated using TGA, XRD and thermodynamic ... -
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 ...
