Abstract
To study the alteration of Portland cement mortar from the El Cabril disposal facility under advective water flow conditions, and to test the applicability of the C–S–H dissolution rate law obtained in our previous study, experiments using columns filled with mortar fragments were performed. Variation of the chemical composition of the output solutions and the analyses of the mortar fragments by means of visual inspection, SEM and X-ray fluorescence (XRF), before and after the experiments, a...
