Abstract
Abstract Curling of concrete remains a major concern in flatwork and its mitigation is critical for crack control, durability, and mechanical performance, not to mention the aesthetics. This report describes a study on concrete slabs that were subjected to a controlled environment of sustained heat and humidity. The resultant curling was evaluated by means of strain gauges placed along the length and breadth of the slab. In addition to the reference plain concrete mix, three fiber reinforced mixes were cast with cellulose microfibers incorporated at a volume fraction up to 0.3 %. The results show that plain concrete will crack and thereby ease the amount of curl whereas the addition of fibers at low dosage rates (<=0.2 %) leads to crack control and consequently, a visible increase in curling. However, at 0.3 % volume fraction, cellulose fibers were able to arrest cracking and also reduce the curl with respect to the reference plain mix.

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
