Abstract

fetched live from OpenAlex

El presente proyecto busca investigar un método de diseño de mezcla para fabricar concreto de alto desempeño que permita construir estructuras cada vez más desafiantes tales como edificios de gran altura, puentes de grandes luces, túneles, etc. El método en el que se basa la investigación es el que propone el profesor Pierre Claude Aitcin de la Universidad de Sherbrooke en Quebec, Canadá, el cual parte con un parámetro nuevo que no se toma en cuenta en los diseños convencionales de concreto: el punto de saturación del aditivo. Este valor, que se obtiene a través de pruebas que se detallarán en el tratado, nos permitirá elegir el aditivo que genere mejor dispersión en una pasta de cemento y las cantidades aproximadas de los componentes de la mezcla. Después se elegirá por criterio de desempeño cuales son los componentes adecuados para nuestros fines. También se realizarán pruebas con materiales cementicios suplementarios a fin de mejorar las propiedades del concreto y también para reducir las cantidades de cemento a usar en el diseño. Se usaran como indicadores de desempeño las recomendaciones y exigencias del ACI 237R-07 “Self - Consolidating Concrete” y la norma europea EFNARC “Especificaciones y Directrices para el Hormigón Autocompactable - HAC”. Después se realizará un análisis costo - beneficio de los concretos especializados, para finalmente mostrar conclusiones y recomendaciones obtenidas de la experiencia.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
