In this paper, we study the possibility of using industrial waste from the coke industry as a feedstock for the production of geopolymer composites. To activate the process of waste polycondensation into a geopolymer, a wet method was used using NaOH, mixture of NaOH and Na₂SiO₃, as well as a dry method with an activator Na₂SiO₃. Fourier transform infrared spectroscopy, thermogravimetry, differential scanning calorimetry, scanning electron microscopy were used to determine the physicochemical features in the obtained geopolymers. It was found that the production of geopolymer composites based on the waste of the coke industry is possible with the use of alkaline activators, the dry method with sodium metasilicate is more preferable.
