Metal concrete composition for molding a concrete element, elements obtained and thermal curing procedure fibers.

The invention relates to a FIBER CONCRETE METALLIC. This concrete is prepared from a composition comprising ELEMENTS Granular thickness sameness to 800 microns SUMO, AND FIBER METALLIC length between 4 and 20 NM, the ratio between the average fiber length and thickness MAXIMO ELEMENTS GRANULAR at most equal to 10 and STILL THE METALLIC fiber volume of 1.0 to 4.0% of concrete volume after setting. FIGURE IS A CURVE OF RESISTANCE OF CONCRETE TRACTION COMPARED WITH A MORTAR classic. The invention also REFERS TO PRODUCE CONCRETE ELEMENTS THAT DO NOT NEED ARMOR METAL SHEET.
