Leaching experiments of uranium(VI) doped calcium-silicate-hydrate (CSH) phases were carried out in a 2.5 M sodium chloride solution and different additions like sodium bicarbonate or sodium sulfate to determine the CSH stability in high saline water. The results were backed up with several spectroscopic techniques like time resolved laser fluorescence spectroscopy (TRLFS), infrared spectroscopy (IR) and powder x-ray diffraction (PXRD) to structural changes of the CSH phases through the leaching.
