Abstract: Concrete consists of a strong cement matrix in which metallic fibers are dispersed. The concrete is obtained by mixing with water a composition comprising: (a) cement; (b) granular components with maximum grain size (D) no more than 2 mm, preferably no more than 1 mm; (c) 'slag' type fillers with particle size no more than 1 microns , preferably no more than 0.5 microns ; (d) components capable of improving the tenacity of the matrix selected from those with average size of no more than 1 mm; and (e) at least one dispersing agent. The concrete meets the following conditions: (f) ratio of water (E) to components (a) and (c) = 8-24 wt.%; (g) fibers have individual lengths (l) of at least 2 mm and l/d ratio (d = diameter) of at least 20; (h) ratio (R) of average fiber length to maximum grain size of granular components = at least 10; and (i) volume of fibers is preferably less than 3.5% volume of concrete. An Independent claim is also included for a pre-mixture for making the concrete.

Abstract: The invention concerns a concrete obtained by mixing with water, cement, granular elements, elements with puzzolanic reaction, constituents capable of improving the toughness of the matrix, metal fibers and at least a dispersing agent, in specified conditions and proportions. Said concrete has improved properties compared to prior art concrete comprising metal fibers.
