For fly ashes with similar chemical compositions, smaller fly ash particles have higher carbonation efficiency and capacity.
“Besides, for fly ashes with similar chemical compositions, the smaller the fly ash particles, the higher the carbonation efficiency and capacity [60].”
From An overview of utilizing CO2 for accelerated carbonation treatment in the concrete industry (2022) · cites this paper as [60]
Increase in temperature from 20 to 80°C significantly accelerated the speed of aqueous carbonation of fly ash, but final CO2 uptake capacity only increased slightly.
“In [60], it was noted that the increase in temperature from 20 to 80 • C significantly accelerated the speed of aqueous carbonation of fly ash, but the final CO 2 uptake capacity only increased slightly (see Fig. 6).”
From An overview of utilizing CO2 for accelerated carbonation treatment in the concrete industry (2022) · cites this paper as [60]
Though rising pressure can promote CO2 solubility in liquid and speed up rate of carbonation reactions, final CO2 uptake capacity and efficiency of fly ash tend to be less affected.
“Different from the above analyzed temperature effect, though rising •Low-calcium fly ash (6.74 % CaO) with maximum particle sizes of 1.0 mm [102] Gas-solid 6 % 28.7 % •High-calcium fly ash (28.42 % CaO) •High temperature of 600 o C [110] Gas-solid 20.7 % -•Flue gas containing both CO 2 and SO 2 from coal-fired power (continued on next page) pressure can promote CO 2 solubility in liquid (see Fig.”

Liquid-to-solid ratio can impact carbonation effect of fly ash in aqueous carbonation.
“Besides, the liquid (water)-to-solid (fly ash) ratio can also impact carbonation effect of fly ash in aqueous carbonation [60,68,103,106,109,116].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
