Abstract

This work is devoted to the issue of ash and slag waste disposal on the territory of the Russian Federation. In Russia, there are up to 1.8 billion tons of accumulated coal waste. They are buried in landfills and harm the environment and humans. The direction for the development of inorganic binders based on industrial waste with low energy consumption and low CO₂ emissions is actively developing. The purpose of this work is to study the process of geopolymerization of industrial waste from the fuel and metallurgical industries. The possibility of activating the structure formation of mixtures based on slag and ash components and the influence of activation parameters on the operational characteristics of the synthesized geopolymer stone are considered. Comprehensive indicators of geopolymer mixtures of different compositions, as well as an artificial composite based on them, have been obtained: normal density, setting time, average density, compressive strength and stretching in bending of a geopolymer stone. The influence of the density of an alkaline activator on the complex characteristics of a geopolymer material has been studied.
