Fe(II) interaction with cement phases: Method development, wet chemical studies and X-ray absorption spectroscopy
Mancini, A.; Wieland, E.; Geng, G.; Lothenbach, Barbara; Wehrli, B.; Dähn, R. (Peer reviewed; Journal article, 2021)Fe(II) interaction with cement phases was studied by means of co-precipitation and sorption experiments in combination with X-ray absorption fine structure (XAFS) spectroscopy. Oxidation of Fe(II) was fast in alkaline ... -
Iron speciation in blast furnace slag cements
Mancini, A.; Lothenbach, Barbara; Geng, G.; Grolimund, D.; Sanchez, D.F.; Fakra, Sirine C.; Dähn, R.; Wehrli, B.; Wieland, E. (Peer reviewed; Journal article, 2021)Slag-containing pastes and concretes were analysed by element-specific synchrotron-based techniques to determine the speciation of iron on crushed materials through spatially resolved micro-spectroscopic studies. The ...
