CO<sub>2</sub>Sequestration in Concrete through Accelerated Carbonation Curing in a Flow-through Reactor
Bibliographic record
Abstract
CO 2 accelerated concrete curing has been recently suggested as a carbon dioxide mitigation technology in which CO 2 is reacted with cement and stored as a thermodynamically stable carbonate in concrete construction products. In this research, the rate and extent of CO 2 uptake by concrete is assessed in a flow-through reactor. Carbonation efficiencies of 16−20% attained in a flow-through reactor was comparable to those obtained for static CO 2 pressure chambers employed in previous studies for accelerated concrete curing. However, significantly less energy is required in a flow-through reactor compared to a CO 2 pressure chamber. Intermittent carbonation experiments showed that the carbonation efficiency was limited in part by slow dissolution and/or diffusion of dissolved reactive components in the concrete matrix.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
