[EN] A concrete in which metallic fibers are dispersed, obtained through mixing with water a composition including a cement; ultrafine elements with a pozzolanic reaction; granular elements distributed into two granular classes (C1)>1 mm and <5 MM AND (C2) ranges from 5 to 15 mm; cement additions; an amount of water E added in the mixture; a dispersant, and preferably a superplasticizer; metallic fibers, in an amount maximum equal to 120 kg per m3 of concrete, the contents of the various components (a), (b), (C1), (C2), (d) and the amount of water E, expressed in volume, meeting the following relationships: ratio 1: 0.50<=(C2)/(C1)<=1.20; ratio 2: 0.25<=[(A)+(B)+(D)]/[(C1)+(C2)]<=0.60; ratio 3: 0.10<=(b)/(a)<=0.30; ratio 4: 0.05<=E/[(a)+(b)+(d)]<=0.75; ratio 5: (d)/(a)<=0.20. The invention applies to the manufacture of voussoirs without frameworks, of tiles and of elements of the plate, shell type or the like. |
