Fiber-reinforced concrete is a promising type of concrete, which in the near future may take a fairly large share in the total volume of concrete produced. Dispersed reinforcement fibers are a versatile material that can be introduced into various types of concrete. This additive may later be as common as plasticizers for modern concrete mixes. Fibro fibers can be used for the production of concrete products in stationary reinforced concrete plants or on-site installations for the production of ready-mixed concrete. The paper examines the influence of parameters on the index of bending strength of the material, as the main one, which is aimed at the introduction of fiber. The results of the influence of the characteristics of dispersed reinforcement on the effectiveness of the introduction of these additives and the final construction and strength properties of heavy concrete are described.
