Abstract
A new analytical approach to determine the ageing creep coefficient of high performance concrete under restrained autogenous deformations is proposed. The results show that changes in creep coefficient under variable stress conditions can be determined from time of setting. These changes were very high shortly after the setting time and decreased to very small changes by the age of two days. The early-age viscoelastic behavior was also found to vary with the quantity of internal curing water provided in concrete through the use of presoaked lightweight aggregate for the prevention of self-desiccation. The early-age creep coefficients determined for high performance concrete under variable stress conditions were found to be more than 50% smaller than those predicted by existing creep models mainly developed from standard compressive creep tests on normal strength concrete. Predictions of developing concrete stresses using the creep coefficients de-termined experimentally with the proposed approach agreed very well with measured stresses.

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
