“…GMB with a size of 500-1500 microns are obtained by pre glass manufacturing in glass furnaces with subsequent dispersion of the melt in the gas stream [3][4][5][6]. GMB intended as a light-reflective element of road marking, obtained by glass manufacturing in gas or electric furnaces, with a refractive index of at least 1.539, have the following chemical composition (wt.…”

The glass micro balls based on glass domestic waste for road construction were obtained. Glass micro balls will reduce the contamination of road marking and increase its light-reflective ability at night. Colorless and colored container glass, as well as lead crystal, was chosen as the starting material for producing glass micro balls. An electric arc plasmotron UPU-8M was used to produce glass micro balls. Pre-crushed fractionated glass together with plasma-forming gas – argon was fed to the powder feeder and from the feeder to the plasma burner. Under the influence of high plasma temperatures, about 9000-12000K, the particles were melted, followed by cooling in the outgoing flow of plasma-forming gases. Due to high-temperature plasma exposure, partial evaporation of alkaline oxides and lead oxide occurred. Glass micro balls were enriched with the oxides of silicon, aluminum and calcium. This helped to increase the acid and alkali resistance of glass micro balls. The micro hardness, density, and refractive index of glass micro balls were studied. It is shown that glass micro balls have an ideal spherical shape and are x-ray amorphous. Glass micro balls are recommended for use in road construction as a reflective element of road marking.

“…Experience with the impact of fuel ashes on cement systems shows positive results [6][7][8][9][10]. Thus, the ash makes it possible to produce concrete for special purposes [11][12][13]. At the same time, ashes in cement binders may exhibit plasticizing and water-holding capacity [14][15][16].…”

The paper provides a comparative assessment of using four types of fuel ashes from different types of coal combustion as additives to replace part of the cement in producing a composite binder. The authors assessed the effectiveness of the additives by cement dough properties (water-binder ratio, normal density, initial setting) and the strength of the binder at 1, 3, 7 and 28 days of hardening. The ashes are ranked according to their efficiency in the structure of composite binder in the following sequence: acid ash from Reftinskaya power plant → acid ash from Novotroitskaya power plant → basic ash from Nazarovskaya power plant → acid ash from Troitskaya power plant. The research revealed that the most effective mineral additives were basic ash from the Nazarovskaya power plant and acid ash from the Troitskaya power plant. Their use reduced the amount of cement by 15% and 25% respectively, while reducing the strength by no more than 3%.

“…They are hollow spheres with a smooth surface, with a diameter of 10 to several hundred micrometers and are characterized by low density (580-690 kg/m³), high strength, corrosion resistance, wear resistance and manufacturability, significant melting point (1400-1550 °C) [16]. The introduction of microspheres not only improves the quality of composite materials, but in some cases provides a reduction in their cost compared to unfilled materials [17][18][19].…”

The influence of the type and quantity of filler on the physico-mechanical properties of polymeric concrete is studied. Microcalcite MK-100 and aluminosilicate hollow microspheres “Granulight 3500” were used as fillers. The properties of the microspheres are determined. The compositions were selected and properties of polymeric concrete when using microspheres instead of micralcite and part of the aggregate (sand) as filler were determined. To preserve the workability of the concrete mixture it is recommended to use chloroparaffin CP-470A as a plasticizer. The optimal composition of polymer concrete with the required workability of the mixture and strength is proposed.
