Title (EN) FIBER REINFORCED CEMENTITIOUS MATERIALS WITH IMPROVED TOUGHNESS AND DUCTILITY
(FR) MATERIAUX CIMENTAIRES RENFORCES PAR DES FIBRES A TENACITE ET DUCTILITE AMELIOREES
Abstract: front page image
(EN)A hybrid fiber reinforcing system that enhances ductility of concrete at small and large crack openings, while avoiding the necessity of using steel fibers at high (e.g., 1 %) volumes, by taking into account Young's modulus, deploying large surface area to volume ratios for improved anchorage, and using different relative lengths.
(FR)L'invention concerne un système de renforcement par fibres hybrides améliorant la ductilité du béton sur de petites et grandes ouvertures de fissure, tout en évitant la nécessité d'utiliser des fibres d'acier à haut volume (par exemple 1 %), par prise en compte du module de Young, étendant de grands rapports surface-volume pour un meilleur ancrage, et utilisant différentes longueurs relatives.
