Nano-modified cementitious composites with high volume supplementary cementitious materials incorporating basalt fiber pellets
Bibliographic record
Abstract
In this study, high performance nano-modified cementitious composites were developed.These composites incorporate 50% fly ash or slag (industrial by-products) replacement of the cement component, 6% nano-silica sol and a new type of basalt fiber strands encapsulated by polymeric resins termed as basalt fiber pellets.The fresh and mechanical properties were investigated for the developed composites with different dosages of basalt pellets (2.5%, 4.5% and 6.9% by volume).Generally, the slag based composites showed improved performance compared to the fly ash based composites.Although the compressive strength of the specimens was reduced with increasing the dosage of pellets, the flexural performance of the composites was significantly enhanced in terms of post-cracking behavior, residual strength and toughness.Composites comprising 4.5% and 6.9% pellets exhibited deflectionhardening behavior.Hence, they have a promising potential for many infrastructure applications.

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.
