    Abstract : FT-IR spectroscopy, powder XRD, 29Si MAS-NMR, 13C CP/1H-decoupling MAS-NMR, BET surface area and CO2-content measurements have been used to study the processes which occur during dry grinding of Ca and Mg silicate minerals: diopside, enstatite, åkermanite, and wollastonite. In the course of grinding alongside to hydration and amorphisation considerable sorption of atmospheric CO2 by ground minerals occur. READ MORE
