Abstract: L'invention concerne un béton de fibres métalliques. Ce béton est préparé à partir d'une composition comprenant des éléments granulaires de grosseur su plus égale à 800 micromètres et, des fibres métalliques de longueur comprise entre 4 et 20 mm, le rapport entre la longueur moyenne des fibres et la grosseur maximale des éléments granulaires étant au moins égal à 10 et le volume des fibres métalliques étant de 1,0 à 4,0 % du volume du béton après la prise. La figure est une courbe de la résistance de la traction du béton comparée à celle d'un mortier classique. L'invention vise notamment à fabriquer des éléments en béton ne nécessitant pas d'armature métallique classique.

Abstract: A metal fiber concrete composition for molding a concrete element, the composition being essentially constituted by a Portland cement, granular elements, fine elements for pozzolan reaction, metal fibers, a dispersing agent, optionally other additives, and water. The preponderant granular elements have a maximum grain size D of not more than 800 micrometers. The preponderant metal fibers have individual lengths 1 lying in the range 4 mm to 20 mm. The ratio R of the mean length L of the fibers divided by said maximum size D of the granular elements is not less than 10. The amount of preponderant metal fibers is such that the volume of preponderant metal fibers lies in the range 1.0% to 4% of the volume of the concrete after setting.
