Bonding of Cement Clinker onto Doloma‐Based Refractories
Bibliographic record
Abstract
Adherence ability of cement clinker on doloma refractories was investigated using a specially designed sandwich test conducted at 1550°C for 30 min, under a load of 5.3 kPa. Fractional factorial experiments determined that silica ratio, particle size, and alumina ratio of raw meal had significant effects on the reactions between the clinker and the refractory. Silica ratio was found to be the most prominent factor influencing the adherence strength of the clinker on the surface of doloma bricks. Doloma refractory, having an excess of free lime, reacts with clinker to form additional C 3 S at the interface, which is greatly beneficial to adherence strength. The interface of doloma/clinker with low silica ratio is covered with a continuous MgO‐enriched layer, which is formed from the CaO reacting with the raw meal in presence of a large amount of liquid phase generated in the clinker. This layer reduced the adherence strength of clinker on doloma. With high silica‐ratio raw meal, clinker and doloma form a C 3 S‐rich layer at the interface, improving strongly the adherence strength of clinker on the brick.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
