Mechanical properties of a carbonate sand from a dredged hydraulic fill
Bibliographic record
Abstract
The ‘Mechanical properties of a carbonate sand from a dredged hydraulic fill’ (Giretti et al., 2018a) together with its companion paper ‘CPT calibration and analysis for a carbonate sand’ (Giretti et al., 2018b) are valuable because there are limited data in the literature on biogenic carbonate sands. ‘Compression of granular materials’ by Mesri & Vardhanabhuti (2009) includes some data on carbonate sands. In laterally constrained compression or isotropic compression, carbonate sands display a type C void ratio against effective stress behaviour for which significant level I and level II particle damage begin at low effective stresses and continue with or without gradual level III particle damage at higher stresses. Level I particle damage includes abrasion or grinding of particle surface asperities, level II particle damage includes breaking or crushing of particle surface protrusions and sharp particle corners and edges, and level III particle damage includes fracturing, splitting or shattering of particles.

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.
