Synthesis and dispersing properties of organosilane-modified superplasticiser in cement–silica fume composite binder
Bibliographic record
Abstract
The impacts of organosilane-modified polycarboxylate superplasticiser (OS-PCE) on the fluidity and hydration performance of a cement–silica fume (SF) composite binder were systematically analysed. It was found that the saturation adsorption amounts of OS-PCE on cement and SF were, respectively, 30.74% and 23.49% higher than those of ordinary PCE and the greater adsorption behaviour of OS-PCE contributed to higher fluidity of the cement–SF binder. The addition of OS-PCE retarded the hydration process of the cement–SF binder proportionally with the dosage of OS-PCE, but promoted the hydration kinetics of the composite binder. The enhancement in reactivity was attributed to well-dispersed SF by the OS-PCE, which provided more nucleation sites for the reaction of heterogeneous calcium silicate hydrates (C–S–H) and enhanced the contact with water to react with calcium hydroxide forming pozzolanic C–S–H. Well-distributed hydration products were identified in the hardened binder with added OS-PCE, with a large number of hydrated gels uniformly filling the pores and gaps, which densified the hardened structure.

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.
