Abstract
The results of research on highly swelling and contractible Pliocene clays are presented in this paper. The introduction of the polymer poly(methyl methacrylate) (with pendant chains possessing organic cations (poly-DEAH + Cl )) into the clay and the dewatering of the clay were performed using the electroosmosis technique. The measurements were made using a simple electroosmosis apparatus equipped with a specially designed anode, with an electric field equal to 0.5 V/cm applied during the process. After the introduction of the polymeric materials into the clay, a more uniform distribution of the water content and a shortening of the dewatering time were observed in the tested samples. In some cases, dehydration in the presence of poly-DEAH + Cl was four times more effective than dewatering carried out without a polymeric additive. Additionally, as pilot measurements have shown, the introduction of a proper amount of poly-DEAH + Cl into the host layers of the clay causes: (i) a decrease in the expansion index, EI, of about 60%; (ii) an increase in the strength parameter, C u (cohesion), of about 50%; (iii) an increase in the internal friction angle, ϕ u , of about 100%; and (iv) a very high decrease in soaking. The claypolymer composite demonstrates high resistance against moisture.Key words: electroosmosis, polymeric additive, electroosmotic dewatering, clay physical properties.

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
