FIELD: construction industry.
SUBSTANCE: invention relates to the field of construction and building materials and can be used in the construction of industrial, civil buildings and structures, including the construction of porches and entrance groups, and elements of building structures. The expected result is achieved by the fact that the reinforced step is a load-bearing structure in the form of a rectangular parallelepiped with one protruding L-shaped rounded side, made of high-strength concrete reinforced with microfiber from secondary nylon with the application of astralene nanoparticles, with a fiber length of less than 0.5 mm.
EFFECT: reducing the cost of construction work, improving the quality of the stage, solving the problem of cracking of the concrete stone of the stage, increase in the resistance of the stone of the stage to bending loads, three-dimensional hardening of concrete is provided.
