Fig. 10: Comparison of the relative mineral abundances determined from XRD and thermokinetic modeling.

a Relative abundance of minerals initially present in the cementitious grout and after experiments. Circles, squares, diamonds and triangles respectively refer to the initial mineralogical composition, and to experiments conducted at atmospheric CO2 conditions, 9% CO2, and 30% CO2. Open symbols: quantities estimated from thermokinetic modeling. Full symbols: quantities estimated from mineralogical (XRD—Supplementary Fig. 4) characterization. b Difference between quantities estimated from the mineralogical analysis and from the thermokinetic modeling. Symbols as in top panel.
