Abstract. The use of waste fibers from the mechanical machining of parts in the formulation of new concretes is of great importance for the protection of the environment because, on the one hand, it makes it possible to recover the materials already used and to on the other hand, it allows nature to be protected from excessive exploitation of the reserve of artificial metallic fibers. The new concretes have high performance (high compressive strength, low porosity and permeability, durability, etc.), however these concretes are fragile and have low tensile strength, which limits their use. The objective of this study is to see the influence of the introduction of waste fibers on the behavior of new concretes. It is necessary to study the physical-mechanical characteristics of these concretes composed of these wastes in the hardened state.
