Geo Polymerization of Kaolin and Metakaolin Incorporating NaOH and High Calcium Ash
Bibliographic record
Abstract
<p><span lang="EN-GB">This research work aims to investigate the possibility to produce Ordinary Portland Cement free construction materials depending on the reactivity of high alkali liquids or solids with rich silica-alumina clay through geo polymerization process. Different mixtures of kaolin, metakaolin, bituminous limestone ash and NaOH were prepared and molded with different ratios. Standard cylindrical samples were prepared from each mixture and cured at ambient laboratory temperature for 28 days to investigate their physical and mechanical properties.</span></p><p><span lang="EN-GB">The unconfined compressive strength results of Kaolin-NaOH mixtures have ranged from 19 to 30 kg/cm<sup>2</sup> after 24 hours. The unconfined compressive strength results of kaolin ash mixtures have ranged from 23 to 36 kg/cm<sup>2</sup> at 28 days. The unconfined compressive strength results of ash-metakaolin mixtures have ranged from 32 to 56 kg/cm<sup>2</sup> at 28 days.</span></p><p class="zhengwen"><span lang="EN-GB">Kaolin-NaOH samples revealed various degrees of efflorescence when subjected to wetting and drying conditions, on the other hand, ash –kaolin samples showed efflorescence free surfaces and increasing of strength with increasing the curing time.</span></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.
