Abstract
The reaction of fresh lightweight concrete with carbon dioxide during early-age carbonation curing is hindered by surface saturation due to vibration consolidation. To promote a high degree of carbonation of fresh lightweight concretes, a dynamic carbonation system was developed to remove surface free water and inject carbon dioxide simultaneously. Based on cement mass, the resulting carbon uptake reached 13% in 4 h carbonation and 20% in 18 h carbonation. The early strength by fresh carbonation is comparable to that of steam curing, while the late strength is higher in a much reduced process time. The dynamic system can effectively control the relative humidity of the chamber to prevent water accumulation and create a route of capillaries for carbon dioxide diffusion and precipitation of carbonates. Dynamic carbonation creates a carbonate–bond matrix. The process provides an excellent means to recycle carbon dioxide, with economic and environmental benefits.

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 it
