Microscopic Analysis for the Oxidation of Sulphide-Bearing Aggregate
Bibliographic record
Abstract
<p>Mortar samples were prepared with sulphide-bearing aggregates and tested for the potential of aggregate oxidation and its subsequent sulphate attack. Scanning Electron Microscopy (SEM) was used as a tool to analyze the developed phases in the samples to confirm that the obtained expansion is attributable to sulphate attack. The Energy Dispersive X-Ray analysis (EDS) of the SEM helped to identify sulphide phases in aggregates and the presence of evidence of sulphate attack in mortars exposed to conditions that promote oxidation and sulphate attack. Ettringite and Thaumasite were detected and confirmed by EDS in the mortars with sulphide-bearing aggregates suggesting that the test conditions are suitable for reproducing the damaging mechanism of sulphide oxidation. </p><p><br></p><p>Elmosallamy, Monaand Shehata, Medhat H.Microscopic analysis for the oxidation of sulphide-bearing aggregate, Journalof Microscopy, SN -0022-2720, https://doi.org/10.1111/jmi.13065<br></p>

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.
