Evaluation of a geosynthetic clay liner water retention curve using vapour equilibrium technique
Bibliographic record
Abstract
The Vapour Equilibrium Technique (VET) has gained popularity as a reliable method for controlling relative humidity as well as vapour suction in various porous media. In this study, super-saturated salt solutions were used to control Relative Humidity (RH) and to infer the water retention curve for a needle punched geosynthetic clay liner with respect to time under free swell and 20 kPa applied stress. Results showed that GCL sample RH plays a key role in moisture absorption/desorption behaviour and equilibration time when RH is in equilibrium with suction. Water absorption isotherms for the bentonite component of GCL agreed well with literature data. It was also observed that the effect of applied stress on water retention was more pronounced at high relative humidity and corresponding low suction. The results presented in this paper can help improve the understanding the water retention behaviour of GCLs in field applications such as waste containment liners and cover systems.

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; both teacher heads agree on what is shown here.
