Abstract
New compositions of geopolymer concrete (GPB) using high-tonnage industrial, man-made and finely ground glass waste have been presented. As part of the scientific research work, the possibility of using waste in combination with an alkaline activator solution (NaOH and Na2SiO3) to obtain geopolymer concrete with high performance was analyzed, and the chemical compositions of all the constituent components were identified. The results of the scientific research work show that the use of finely ground glass waste as a partial substitute material for sand in the composition provides sufficient mechanical properties, as well as shrinkage, where when the GPB dries, it decreases with an increase in the content of finely ground glass. The composition of GPB was developed with a ratio of water to binder equal to 0.35. In addition, the tests demonstrated an improvement in compressive and flexural strength characteristics with an increase in the glass component content to an optimal value. In the future, it is planned to expand the research taking into account different temperature and climatic conditions of operation. This will make it possible to adapt the developed GPB compositions to specific construction tasks
