    A steel block is subjected to cutting in a direct manner to produce steel fibres for reinforcing concrete. The said fibres are flat in shape and satisfy the following predetermined conditions:- if L is the length of a steel fibre, W is its width, t is its thickness, and N = W/t is the flatness index; then, L is 20 to 40 mm, N = W/t is 7 to 9, W is 1.5 to 2.5 mm, and t is 0.2 to 0.3 mm.

    one
    The invention relates to the manufacture of building products from concrete reinforced with disperse reinforcement.
    The aim of the invention is to improve the manufacturability of the reinforcing element and improve its adhesion to concrete.
    Figure 1 shows the reinforcement element of a general view; figure 2 - the same cross section.
    The reinforcing element for dispersed reinforcement of concrete is steel chips 1 with a smooth one surface 2 and with a wavy relief on its other surface 3. One longitudinal edge 4 is made pointed, the other opposite its edge 5 is rounded towards the smooth surface 2. is 20-40 mm, width 1.5-2.5 mm, thickness Oj2-0.3 mm, and the ratio of its width to thickness 7-9.
    When mixing reinforcing elements with concrete, uniform mobility of the mixture and uniform distribution of elements in concrete are provided. At the same time, the elements have elastic properties with sufficient strength and elasticity, as a result of which, when subjected to bending moment, the elements do not bend or break when mixed. In addition, the elements have satisfactory coupling.
    with concrete, which excludes their separation from concrete or settling to the bottom of the form.
    The invention improves the manufacturability of the reinforcing element and improves its adhesion to concrete by eliminating destruction when mixed with concrete and preventing the formation of lumps, as well as by improving its adhesion to concrete, due to the optimum ratio of its dimensions and surfaces. smooth and grooved. | g Noah sides.

    Invention Formula
    The reinforcing element for dispersed reinforcement of concrete, containing steel shavings with a wavy relief on one of its surfaces and with a pointed one of its longitudinal edges, characterized in that, in order to improve the manufacturability of its production and improve adhesion with concrete, the other surface of the chip is made smooth and the opposite edge of the pointed one is rounded towards the smooth surface of the chip, the chip length being 20-40 mm, width 1.5-2.5 mm, thickness 0.2-0.3 mm, and the ratio of its width to thickness 7-9.
