摘要

"Material comprising an inorganic matrix as cement, mortar, plaster and concrete, reinforced by fibers and cement type products.The invention concerns materials comprising an inorganic matrix such as cement, mortar, plaster or concrete reinforced by fibers, which can be used in various types of products.Such as building materials, for example, flooring, tiles, water tanks and pipes, in particular for disposal of used water.In particular, the polyamide micro fibers of reinforcement of cement of the invention are preferably a title less than or equal to 1 dtex, a elastic modulus greater than 1 GPa.An elongation at break of between 8 and 100% and the tenacity of between 30 and 100 CN / tex.The high modulus of these fibers increases the tension after rupture of the products and allows for a greater ductility.The reinforcing fibers are spun in a faulty flow reduced by capillary and then subjected to high rates to obtain high modulus fibers and low titer.
