Abstract

fetched live from OpenAlex

L’incorporation de fines naturelles algériennes en tant qu’addition minérale dans les bétons autoplaçants (BAP) constitue une voie de valorisation écologique et économique. Un programme expérimental a été établi afin d’étudier les comportements mécanique, instantané et différé, de trois bétons autoplaçants de même formulation et ne différant que par la nature des additions minérales. L’étude de ces bétons à l’état frais montre un respect des recommandations de l’Association française de génie civil (AFGC). Les résistances mécaniques en compression supérieures en présence de pouzzolanes naturelles et fines siliceuses. Les déformations différées des BAP formulés avec fines algériennes sont globalement du même ordre de grandeur que celle du BAP avec filler calcaire. La comparaison avec des déformations différées sous charge en mode dessiccation d’un béton vibré de classe de résistance proche montre une déformabilité légèrement plus forte des BAP. Enfin, la confrontation avec les prédictions du modèle Eurocode 2 révèle une sous-estimation des amplitudes des déformations différées.

Not 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.
