To reinforce products made from hydraulic binder agents, fibers of polymerized acrylic nitrile, which are manufactured with a molar concentration of acrylic nitrile units of at least 98%, are used. The fibers advantageously have a strength of at least 50 cN/tex and a breaking elongation of at most 15%. These fibers produce a product after setting having good bending tensile strength and excellent impact strength. |
