The possibility of using glass waste as a binder for glass concrete is investigated. Today, the construction industry makes new demands on binders, along with the improvement of the production of Portland cement. The research is underway to study new types of binders. Disposal of glass waste is due to environmental and economic prerequisites. In the work, studies of the properties of glasses for obtaining binders are carried out. Using the X-ray fluorescence method, the chemical composition of container and sheet glass has been investigated, and the main oxides of the feedstock have been determined. An activating component has been selected for a composite binder. On the basis of experimental data, it is found that the most expedient use as an activator of water glass in an amount of 5% by weight of the composite binder. It is found that glass filler must be used in combination with cement to obtain a composite binder, since alkaline agents Na2CO3 and Na2SiO3 do not work as activators for glass powders. The optimal compositions of the composite binder have been determined and the strength properties of the obtained samples have been studied in detail. Compositions with an activator Na2SiO3 shows the highest strength indicators than compositions with an activator Na2CO3.

An effective energy-saving technology for producing composite glass-crystal facing materials based on fractionated cullet of sheet and container glasses, cullet of porcelain and sodium liquid glass has been developed. The use of fine porcelain powder in the composition of composite glass-crystal facing materials in an amount of up to 10 wt is justified. % and liquid sodium glass up to 5 wt. %. It is shown that the optimal fractional composition of granulated mixed cullet is 35 wt. % fraction 0.63-0.80 mm; 35 wt. % - fractions of 0.80-1.25 mm and 30 wt. % fraction of 1.25-3.15 mm. Polytherms of viscosity of colorless, green and brown container glasses, as well as sheet glass, are calculated. The possibility of using mixed cullet for obtaining composite glass-crystal facing materials is on the basis of obtained dependencies. The chemical composition of sheet and container glasses and porcelain is studied using x-ray fluorescence analysis. Optimal charge compositions have been developed to obtain glass-crystal materials with compressive strength up to 79 MPa. The technology of obtaining composite glass-ceramic facing material includes the following technological operations: milling of glass breakage; grinding cullet of porcelain; drying of sodium liquid glass; the screening of crushed cullet on fractions; the grind of crushed cullet of China; grinding the dried sodium silicate glass; weighing the components in accordance with the developed formulations, the averaging of the graded cullet with fine porcelain; averaging the mixture of finely ground dried sodium silicate glass; stacking the mixture in a metal mold; compaction of the mixture in metal molds; heat treatment in a muffle furnace (sintering); extraction of facing tiles from molds; trimming the edges of the tiles with a diamond saw; quality control of finished products.

The practical use of boron and its compounds is extremely diverse due to its different properties. About 55 % of boron raw materials are consumed by the glass and ceramic industries for the manufacture of optical glasses, heat-insulating glass fibers, acid-resistant and refractory products, enamels, glazes, porcelain, etc. The paper considers the possibility of using colemanite to obtain enamel over steel. The optimal temperature-time regime of firing has been developed to obtain a high-quality coating and achieve the desired effect. It has been established that colemanite can partially replace cover enamel drill. On the basis of the studies carried out, it was found that the obtained experimental enamel is more refractory than the ESP-210 enamel. The optimal firing temperature for the experimental coating was established – 950 ° С, for the ESP-210 coating – 825 ° С. For uniform reflow of the experimental coating, a temperature is required that exceeds the reflow temperature of ESP-210 by 125 ° C. Colemanite-containing batch was cooked. Cooking was carried out in an electric oven at 1300 ° C for 5 hours. For further research, a slip was prepared from the experimental enamel and applied by pouring onto the plates
