Time-dependent load-induced deformation of Ca(OH)<sub>2</sub>
Bibliographic record
Abstract
Short-term time-dependent strains were monitored on calcium hydroxide compacts having a porosity of 19·7%. The creep experiments were conducted in a controlled environment chamber maintained dry (0% RH) at 22 ± 2°C with nitrogen purging. Prior to loading, the compact specimens were vacuum dried at 105°C for 3 h (equivalent to D-drying). The applied stress for the creep test corresponds to 5% of the compaction pressure (386 MPa). The Ca(OH) 2 compact specimens were in the form of T-shaped columns with a minimum thickness value (for the web and flanges) less than 1·2 mm. The AC impedance spectra of loaded and unloaded Ca(OH) 2 compact specimens were also monitored in real time. This was achieved by the coupling of the impedance analyser to the creep experiment. An assessment of the relevance of the high frequency arc depression angle obtained from the impedance analysis to an understanding of the load-induced deformation behaviour of the Ca(OH) 2 compacts was made.

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; both teacher heads agree on what is shown here.
