Abstract
Abstract In this paper, temperature data collected by thermocouples embedded into concrete over a period of 10 years are analyzed for a concrete slab and beam located outdoors near Kingston, Ontario. Temperatures measured in the concrete are compared with temperatures encountered in ASTM C 666 Resistance of Concrete to Rapid Freezing and Thawing and ASTM C 1293 Standard Test Method for Concrete Aggregates by Determination of Length Change of Concrete Due to Alkali-Silica Reaction. The average number of freezing and thawing cycles at the site was counted using different freezing and thawing temperature criteria as presented in the literature by various authors. Results are compared with data from a second site. The rates of freezing and thawing occurring at the outdoor exposure site were found to be significantly less than specified in the ASTM C 666 laboratory test. Average daily maximum temperatures in July were at approximately 33°C at depths of 50 mm in the concrete.

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
