A Preliminary Study of the Bentonite Self-Healing of Slits in a GCL upon Full Hydration
Bibliographic record
Abstract
The experiments reported herein examine the self-healing of slits in GCLs upon hydration with deionized water under a confining stress of 2 kPa. Consideration is given to self-healing of 15 mm-wide, 25 mm-wide, and 30 mm-wide × 120 mm-long single slit in the center of a GCL specimen. The single 15 mm-wide slit fully self-healed after 65 days. Neither the 25 mm-wide × 120 mm-long nor 30 mm-wide × 120 mm-long single slit fully self-healed and a fully penetrating hole remained after full hydration. The self-healing of GCL specimens with 15 mm-wide × 240 mm-long double parallel slits is also examined. Full self-healing was observed when there was a 20 mm-wide strip of undamaged GCL between the slits. However full self-healing did not occur when the widths of this strip of bentonite between slits was reduced to 10 mm and 5 mm. This study also raises a number of questions such as what is the effect of stress, hydrating conditions, and mass of bentonite in the GCL that require further investigation.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
