Abstract
This study compared the performance of various maturity functions based on the calculated age conversion factor, equivalent age, estimated strength and setting time of concrete mixtures using laboratory and field data. The influence of varying dosages of the particular retarder on the apparent activation energy and temperature sensitivity factor associated with the Freiesleben Hansen and Pederson, and Carino and Tank, maturity functions was found to be negligible. As expected, the influence of the apparent activation energy in the Freiesleben Hansen and Pederson function was found to depend on the deviation of average concrete temperature from the reference temperature. The performance of maturity functions depended on the temperature–time history of concrete in both laboratory and field conditions. Based on this study, calculated age conversion factors, equivalent ages and estimated strength development based on the two functions differ from those obtained using the Rastrup, Weaver–Sadgrove, and Nurse–Saul functions. All maturity functions predicted initial setting time reasonably well with varying retarder dosages and initial concrete temperature in both field and laboratory conditions.

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
