Cold plasma activated CO2 desorption from calcium carbonate …
RGA measurements were recorded while the DBD reactor was operated in air over calcium carbonate (10.0 g) or α-Al 2 O 3 powder (10.0 g), the latter serving as the control. Fig. 3 shows the RGA signals of the desorbed CO 2 and other key species (O 2, NO, N 2 /CO – note that N 2 cannot be distinguished from CO).

Hydration of cement pastes with calcium carbonate polymorphs
The amount of calcium carbonate that has reacted in cement is usually ∼1–2 wt% [68], which can be within the variations of the QXRD method. Therefore, any minor amount of calcium carbonate reacted may not be easy to detect. Over time, the total amounts of calcium carbonate in the cement pastes were nearly unchanged.
