The Use Of Wollastonite to Enhance Fresh and Mechanical Properties of Concrete
Bibliographic record
Abstract
Wollastonite is a natural material that consists of calcium silica oxides. This research program focused on evaluating the feasibility of using wollastonite in concrete or mortar. The experimental program for this study is designed to investigate the strength conribution for mortar cubes with wollastonite at 5 and 10% replacement of sand or Porland Cement (PC). The compressive strength has shown remarkable improvment in all ages compared with control mix when there was 5% sand replacement. The study also tested the compresiive strenght for concrete with the same levelsof wolllastonite as in mortar. The compressive strength fo cyclinders having 5% and 10% wollastonite powder as cement replacement was not improved compared with the control mix. Furthermore, the study tested the possibility of using wollastonite as mineral filler in Self Consolidation Concrete (SCC). Mixture of SCC were designed with the levels 0, 8, 10% of wollastonite powder. The fresh properties were evaluated using the slump flow.

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.
