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.

Abstract: A concrete includes organic fibers, dispersed in a cement matrix. The cement matrix includes elements having predetermined particle sizes. The organic fibers have predetermined lengths and diameters. The behavior of the concrete is improved both with respect to the occurrence of minute cracks and the propagation of large cracks as a result of a synergistic effect between the cement matrix and the organic fibers.

Abstract: Concrete comprises organic fibers dispersed in a hardened cement matrix. Concrete comprising organic fibers dispersed in a hardened cement matrix is obtained by mixing with water composition comprising fibers and: (a) cement; (b) granular components with maximum size, D, of no more than 2 mm, preferably no more than 1 mm; (c) fine components from ash with size no greater than 20 microns preferably no greater than 1 microns ; and (d) at least one dispersing agent; said composition meeting the following conditions: (e) wt. % water with respect to total weight of (a) and (c) = 8-25; (f) organic fibers have individual length, l , of at least 2 mm and ratio l\/ phi ( phi = diameter) at least = 20; (g) ratio, R, of mean length of fibers to D at least = 5; and (h) quantity of fibers is such that their volume represents no more than 8% total volume of concrete. An Independent claim is also included for pre-mixture for preparing cement matrix for making said concrete.

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.
