Chloride sorption by C-S-H quantified by SEM-EDX image analysis

The validation of reactive transport models requires the understanding and quantification of the chloride sorption by C-S-H, but the experimental methods are lacking. In this paper, we use SEM-EDX hypermaps to quantify the chloride sorption in hydrated an C3S paste, after equilibrium in solutions of chloride salts (NaCl, KCl, CaCl2, MgCl2), with and without the addition of sodium hydroxide. The errors and uncertainties of the method are analysed...
