Abstract
The areas of use of glass domestic waste in the building materials industry are considered. The possibility of obtaining a facing and decorative material-smalt based on colored container and high-quality glass is considered. An innovative technology has been developed for the production of smalt based on finely ground powders of colored container glass using 20%, 40% and 60% liquid glass as a humidifier. The dependences of the influence of various concentrations of aqueous solutions of liquid glass on the degree of compaction of smalt are established. It is shown that the addition of aqueous solutions of liquid glass to the glass powder before pressing reduces the firing temperature from 775 to 725 ° C. the influence of different concentrations of aqueous solution of liquid glass in the initial charges on the chemical composition of the smalt is investigated. The elemental composition of smalt is studied using the x-ray fluorescence method. The microstructure of smalt made from a mixture with an optimum content of 40% aqueous solution of water glass is investigated. The effect of various concentrations of liquid glass on the microhardness of smalt is provided. It is shown that when the content of 40% liquid glass in an aqueous solution, the microhardness reaches maximum values.

Summary
Проанализированы области использования стеклянных бытовых отходов в промышленности строительных материалов. Разработана инновационная технология получения смальты на основе тонкоизмельченных порошков цветного тарного стекла с использованием в качестве увлажнителя водных растворов 20-%, 40-% и 60-% жидкого стекла. Исследовано влияние различной концентрации жидкого стекла на микротвёрдость смальты. Шухова на кафедре технологии стекла и керамики выполнены многочисленные исследования и разработаны технологии по получению облицовочных, теплоизоляционных и стеновых материалов с защитно-декоративными покрытиями с использованием стеклянных бытовых отходов. Разработан ряд технологий изготовления стеновых строительных материалов автоклавного твердения с защитно-декоративными покрытиями на основе тонкоизмельченных цветных тарных стёкол [7]. В настоящее время продолжают проводиться исследования в области разработки технологий изготовления различных строительных материалов на основе стеклянных бытовых отходов [16, 17]. Основными сырьевыми материалами для изготовления смальты служили цветные тарные стёкла синих, оливковых, изумрудных, тёмно-зеленых и различных. Отожженные таблетки мышленных масштабах не перерабатывается. подвергали исследованию на микротвердость
