FIELD: chemistry. ^ SUBSTANCE: method relates to portland cement-based concrete with metal reinforcement, and specifically in form of dispersion-reinforcement elements. The method of aligning metallic dispersion-reinforcement elements in concrete involves preparing concrete, adding metallic dispersion-reinforcement elements and pouring the concrete mixture into a vibration mould. An aggregate with fineness modulus 1, 1.5, 2 is added to the concrete. Dispersion-reinforcement elements with diameter 1-2 mm and length 30-60 mm is added while mixing constantly. The obtained mixture is then poured into a vibration mould and simultaneously exposed to vibration and an electromagnetic field with induction 0.12-0.36 T. ^ EFFECT: improved operational properties, low material consumption, automation of production lines for producing concrete articles, providing dispersion-reinforcement elements contained in a concrete mixture, needed for spatial orientation which meets operating conditions of the structure. ^ 1 dwg |
