Abstract

In most cases, fiber reinforced concrete (FRC) contains only one type of fiber. The use of two or more types of fibers in a suitable combination may potentially not only improve the overall properties of concrete, but may also result in performance synergy. The combining of fibers, often called hybridization, is investigated in this paper for a very high strength matrix of an average compressive strength of 85 MPa. Control, single, two-fiber and three-fiber hybrid composites were cast using different fiber types such as macro and micro-fibers of steel, polypropylene and carbon. Flexural toughness tests were performed and results were extensively analyzed to identify synergy, if any, associated with various fiber combinations. Based on various analysis schemes, the paper identifies fiber combinations that demonstrate maximum synergy in terms of flexural toughness.

Résumé

Dans la plupart des cas, le béton renforcé de fibres (BRF) contient seulement un type de fibre. L'utilisation de deux types ou plus de fibres dans une combinaison appropriée peut potentiellement non seulement améliorer les propriétés globales du béton, mais peut également avoir comme conséquence la synergie d'exécution. La combinaison des fibres, souvent appelée hybridation, est étudiée dans cet article pour une matrice de très haute résistance, d'une résistance à la pression moyenne de 85 MPa. Des composés hybrides de contrôle et à une, deux et trois fibres ont été moulés en utilisant différents types de fibre telles que les macrofibres et les microfibres d'acier, du polypropylène et du carbone. Des essais de ténacité en flexion ont été réalisés et les résultats ont été intensivement analysés pour identifier la synergie, le cas échéant, liée à de diverses combinaisons de fibres. Basé sur divers arrangements d'analyse, le papier identifie les combinaisons de fibres qui démontrent la synergie maximum en termes de ténacité en flexion.
