Abstract
Abstract This study investigates the effect of various microfillers on the abrasion resistance of metakaolin‐based, geopolymer composites. Comparative tests were conducted on a baseline geopolymer and composites reinforced with chamotte powder, basalt microfiber, prestressed, solid, basalt glass microspheres (PSBGM), and their combinations. Abrasion resistance was evaluated according to ASTM C501‐21 using the Taber Abraser. The results demonstrate that prestressed, solid, basalt glass microspheres significantly enhance wear resistance, both individually and in combination with chamotte powder or basalt microfiber. Quantitative analysis indicates that basalt‐based microfillers enhance abrasion resistance by a factor of 3 to 4. This is due to the high surface microhardness of prestressed, solid, basalt glass microspheres, produced using the superheated melt method, which is approximately 7.1 GPa on the Vickers scale. These results confirm the potential of basalt microfillers and geopolymer matrices for developing highly wear‐resistant, fully inorganic, composite materials, coatings, and repair mixtures.

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 it
