Abstract
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.

Summary
В работе проводились исследования свойств стекол для получения вяжущих. Установлено, что стеклянный наполнитель необходимо использовать в сочетании с цементом для получения композиционного вяжущего, так как для стеклопорошков щелочные агенты Na2CO3 и Na2SiO3 не работают как активаторы. Разработка составов и материалов для строительной промышленности с применением стеклоотходов вызвано экологическими и экономическими положениями. Проблемы рационального использования цемента в бетоне и изделиях на его основе являются весьма актуальными, в этой связи необходима разработка композиционных материалов с использованием смешанных вяжущих, а также внедрение такой технологии, которая гарантировала бы высокие эксплуатационные характеристики композитов [13]. Для проведения экспериментальных исследований были использованы следующие сырьевые материалы: портландцемент марки ЦЕМ I 42,5Н производства ЗАО «Белгородский цемент» (ГОСТ 10178–85); песок Корочанского месторождения (ГОСТ 8736–2014); вода (ГОСТ 23732–2011), стеклобой листового и тарного стекол.
