The article describes a partial solution to the problem of disposing of waste plastic as their use in the manufacture of fiberglass reinforcement. The comparison of the calculation of the foundation slab reinforcement using the class A-500S and fiberglass reinforcement with a thickness of 300 mm plate. From calculations that by recycling the plastic in the manufacture of fiberglass reinforcement observed economic benefits for the producer (cost of fiberglass reinforcement with the same thickness of the foundation plate 3 times less than steel), as well as environmental benefit for the planet, as this will help reduce the amount of plastic waste without recycling.

The paper presents a classification of two-dimensional as well as three-dimensional fractals, fractal characteristics, methods for modeling fractals. The algorithm of visualization fractals have used in the "3D simulation of fractals" software for the first time. The points’ generator module unites the points of space into a set of triangular finite elements in the environment of the computing complex SCAD. Complex fractal geometry have transformed into a spatial finite element model of the fractal.

The effect of sodium chloride concentration on the job ORTA electrodes. It is found that the electrodes OPTA, especially in the sodium chloride concentration below 50 g/liter, three groups occur conjugate processes, oxidation of chloride ions, the solid-phase oxidation of the anode material, dissolution of the active catalytic coating. The processes of oxidation of chloride ions prevail in current densities of 0.001 - 0.032 A/cm2 at high current densities become essential processes of oxidation of the ruthenium oxide coating. The oxidation of chloride ions, especially at concentrations less than 50 g/liter can be described as occurring in a constantly evolving anode active material due to its corrosion and solid-phase oxidation.
