Physicochemical Impacts of In-Situ Mineralized CaCO3 on Very Early Hydration of Cement at Two Temperatures

Monkman, Sean, Kenward, Paul, Dipple, Greg·2023·ACS Sustainable Chemistry & Engineering

Abstract

The addition of carbon dioxide to ready-mix concrete can improve its performance through in-situ mineralization of calcium carbonate. A model system of an oil-well cement paste mixed with and without additions of CO 2 gas was investigated to characterize the impacts of in-situ CO 2 mineralization on the first 15 min of hydration at 4 and 24 °C. Impacts were examined through aqueous chemistry, total inorganic carbon (TIC), stable isotope 13 C/ 12 C fractionation, loss on ignition (LOI), and scanning electron microscopy (SEM). It was demonstrated that the calcium and silicon concentrations increase immediately after the CO 2 input and declined within the first few minutes. TIC testing confirmed that the mineralization was rapid and brief with no evidence of increasing carbonate formation in the minutes after the CO 2 input. Isotope fractionation confirmed that the carbonates formed were attributable to the mineralization of gaseous CO 2 . The loss on ignition testing showed that the CO 2 -activated system had greater mass gain (bound water and bound CO 2 ) over 15 min of hydration than did the reference. SEM observations identified carbonate reaction products <200 nm immediately after the CO 2 injection. Gel products were formed over the ensuing 15 min. The temperature of the testing had little impact other than to increase the concentrations of Ca and Si in solution and increase the amount of mineralized CO 2, as associated with the higher solubility of CO 2 in water as the te…

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Stable isotope analysis (13C/12C fractionation) demonstrated that newly formed carbonates in oil well cements originated directly from the injected gaseous CO2, confirming the source and mechanism of mineralization.

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.
