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.

“…The investigation and development of materials based on alkali-activated binders using natural and artificial sources of aluminosilicates, the geopolymer binders, have been studied by many world scientific schools, including in Russia, Ukraine, Iran, the Czech Republic, Germany, France, Poland, Australia, Spain, the USA, and China. The processes of structure formation of geopolymers are described in detail in [4][5][6][7][8][9][10][11][12].…”

Developing Environmentally Sustainable and Cost-Effective Geopolymer Concrete with Improved Characteristics

et al. 2021

Improving the efficiency and quality of construction mainly depends on the cost of building materials, which is about 55–65% of total capital-construction costs. The study aimed to obtain geopolymer fine-grained concrete with improved quality characteristics that meet the construction field’s sustainable development criteria and that have environmental friendliness, economic efficiency, and advantages over competing analogues. The dependences of strength characteristics on various compositions of geopolymer concrete were obtained. It was found that the most effective activator is a composition of NaOH and Na2SiO3 with a ratio of 1:2. The increase in the indicators of the obtained geopolymer concrete from the developed composition (4A) in relation to the base control (1X) was 17% in terms of compressive strength and 24% in tensile strength in bending. Polynomial equations were obtained showing the dependence of the change in the strength characteristics of geopolymer concrete on the individual influence of each of the activators. A significant effect of the composition of the alkaline activator on the strength characteristics of geopolymer fine-grained concrete was noted. The optimal temperature range of heat treatment of geopolymer concrete samples, contributing to the positive kinetics of compressive strength gain at the age of 28 days, was determined. The main technological and recipe parameters for obtaining geopolymers with the desired properties, which meet the ecology requirements and are efficient from the point of view of economics, were determined.
