Deformation Behaviour of Geopolymer Mortars with Alkali-reactive Carbonate Aggregate
Bibliographic record
Abstract
For understanding the alkali-carbonate reactivity in geopolymer and the mechanism of traditional alkali-carbonate reaction(ACR),the deformation behavior of geopolymer mortar with pure dolomite(YT) and dolomitic limestone from Kingston,Canada(CK) was studied by curing at different conditions,i.e.room temperature with over 95% relative humidity(RH),38 ℃ RH 95% and 80 ℃ 1 mol/L NaOH.Results show that,at the three curing conditions,YT only acts as a filler to slightly reduce the shrinkage of the mortar;The deformation behavior of geopolymer mortar with CK varies remarkably with the changes in the curing temperature and alkalinity,especially the mortars with CK expand slightly at different curing stages when cured at 38 ℃ RH95% and 80 ℃ 1 mol/L NaOH;it suggests that the reaction mechanism of CK in geopolymer may be quite different with that in cement system,and the shrinkage of geopolymer might be compensated by selecting special carbonate aggregate and curing conditions.

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.
