The novel liquid fuel 2-dimethylaminoethyl azide (DMAZ) is a good candidate for the replacement of the hydrazine family in space programs. However, it suffers from low electrical conductivity, which is dangerous during the production process and its transportation. A simple and effective way to increase its electrical conductivity is the use of antistatic additives. In this article, the electrical conductivity of DMAZ was initially predicted via an artificial neural network. Then, the increase in electrical conductivity of DMAZ was investigated using some chemical surfactants (such as hexylamine, octylamine and tributylamine), acetonitrile as a polar aprotic substance and a DMAZ salt (DMAZ·HCl) as an ionic liquid. Of these additives, acetonitrile had the greatest effect on the electrical conductivity of the fuel, exhibiting an increase in conductivity of about 45%. Adding a two-component mixture of acetonitrile and the DMAZ salt, further increased the electrical conductivity of the fuel by about 55%, relative to pure DMAZ. Tributylamine did not have a significant effect on the electrical conductivity of the fuel.

The impact of thermal power plants on the environment depends largely on the type of fuel. Coal is most polluted of all energy sources and making the largest contribution to global climate change. In coal power plants account for the biggest share of greenhouse gas emissions in the energy sector, as they have the highest rate of release of carbon dioxide per unit of electricity produced compared with all other fossil fuels. When burning coal into the atmosphere large quantities of solid particles containing not burned carbon oxides and heavy metals emitted as carbon monoxide (CO) and toxic organic compounds, including dioxins and benzopyrene, have carcinogenic effect, fly ash, sulfur and sulfuric anhydride, nitrogen oxides, some amount of fluoride and gaseous products of incomplete combustion. So especially harmful condensation power plants working on low-grade fuels. Among these stations applies Burshtyn TPP. The aim of this work is to study the technology of production of expanded concrete possibility of replacing cement ash Burshtyn thermal power station, strength of the samples and kinetics of hardening.
