Méthode simplifiée de formulation d’un béton à haute performance avec et sans fibre métallique

Abstract: Résumé. Le présent travail, propose une méthodologie simplifiée, s'appuyant sur des méthodes de formulation de béton connues dans la littérature et sur des essais d'optimisations au laboratoire, permettant la détermination d'une composition d'un béton à haute performance « BHP » et de béton de fibre à haute performance « BFHP ». Pour ce faire, une large caractérisation (physique et mécanique) des matériaux utilisés a été conduite. Suivie d'une étude préliminaire, ayant pour objectif d'optimiser le dosage en Su… Show more

“…This is achieved primarily by lowering the W/C ratio by a superplasticizer and adjusting the granular extent by adding ultra-fine minerals. These fillers play a dual role in concrete by increasing the compactness by filling micro-pores, on the one hand, and on the other hand providing chemical reactions with the other materials, which participate in the formation of secondary hydrates and consequently improves the resistance and durability [12]. HPCs are characterized by a marked improvement in durability performance, resulting from extremely reduced porosity.…”
