Abstract
Abstract The effect of specimen composition on the physicochemical processes in cemented paste backfill is studied using small perturbation electromagnetic waves. The factors that are tested include binder type and content, selected chemical admixtures (superplasticizers), mineral additives (e.g., fly ash), and pore fluid chemistry (e.g., ionic concentration and pH). Two measurement techniques are used: a two-electrode capacitor-type system at low frequencies (100 Hz to 100 kHz) and an open-ended coaxial termination probe at high frequencies (200 MHz to 1.3 GHz). The electromagnetic measurements are sensitive to changes in the CPB composition. The temporal variations in the effective conductivity reflect the various hydration stages, while the decrease in the real relative permittivity with time is due to a reduction in free water content.

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
