Prospects for the Synthesis of Silicate Geopolymer Materials Based on Ash and Slag Waste from Thermal Power Plants in the Russian Arctic Zone

Abstract

The issues of ecology and economics of the use of solid organic fuels for the production of thermal and electric energy, as well as the disposal of their combustion products, are becoming more and more relevant not only in our country, but also in world practice. The formation of industrial waste, in particular ash and slag waste, creates a number of difficulties. One of the main ones is a violation of the environment, which is also relevant for the Arctic zone of the Russian Federation. On the territory of the Arctic zone of the Russian Federation, along with hydroelectric power plants, nuclear power plants and thermal power plants operating on gaseous and liquid fuels (fuel oil), a significant share (on average, at least 20%) is taken by coal generation. An equally urgent problem of the Arctic zone of the Russian Federation is the problem of road construction in permafrost conditions and extreme climatic conditions.
