Abstract
Xonotlite forms under hydrothermal conditions and it dehydrates to β-wollastonite between 770 and 800 °C under atmospheric pressure. The solubility of xonotlite is poorly known, as the experimental datasets reported in literature differ by as much as 10 log units. This study investigates the impact of temperature (7, 20, 50 and 80 °C) on the solubility of xonotlite by dissolution experiments from undersaturation. The derived solubility data are comparable to those reported in literature at 25 °C for synthesized xonotlite, while the much higher solubility reported in literature for natural xonotlite seems to describe the solubility of amorphous C-S-H. The solubility of xonotlite increases moderately at lower temperature. At 7 °C, xonotlite was found to co-exist with tobermorite.
