Minimum strength required for resisting cyclic softening/failure of cemented paste backfill at early age
Bibliographic record
Abstract
This paper attempts to assess empirically the liquefaction susceptibility of cemented paste backfill (CPB) at early age (£ 7 days). Early age CPB can be categorized as a “clay-like” material because their plasticity index, PI ³ 5 (PI = Liquid Limit, LL – Plastic Limit, PL). For clay-like material such as CPB, the liquefaction susceptibility can be characterized by the “cyclic softening” or “cyclic failure” which is assessed using an empirical method developed for clays and clay-like materials. This analysis allowed determining the minimum undrained shear strength required to resist cyclic softening (failure) of cemented paste backfills which is directly related to the unconfined compressive strength (UCS).

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.
