Consolidation characteristics of early age cemented paste backfill
Bibliographic record
Abstract
a Industrial NSERC – Polytechnique – UQAT Chair on environment and mine waste management b Canadian Research Chair on integrated management of sulphidic mine wastes by means of backfilling This paper presents a laboratory study undertaken to understand the effect of binder contents (0-control sample, 1, 3, 4.5 and 7 wt%) on one-dimensional (1-D) consolidation properties (e.g., coefficient of consolidation cv, compression index Cc and recompression index Cr) of cemented paste backfill (CPB) at curing ages of 0, 1, 3, and 7 days. Test results show that the behaviour of 1-D consolidation under time-dependent loading is greatly affected by the amount of binder used within CPB. Cc varies from 0.06 to 0.54 while Cr is between 0.0019 and 0.0081. cv decreases from 2.73x10-3 to 3.46x10-3 cm2/s over time due to the gradual formation of cement bonds during hydration. RÉSUMÉ Cet article présente une étude expérimentale entreprise pour comprendre l'effet de la proportion de liant (0-échantillon témoin, 1, 3, 4.5 et 7%) sur les propriétés de consolidation unidimensionnelle (coefficient de consolidation cv, indice de compression Cc et indice de ré-compression Cr) de remblai en pâte cimenté aux temps de curage de 0, 1, 3, et 7 jours.

How this classification was reachedexpand
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.
