In the European Union, the Russian Federation, as well as in a number of other countries, cement production is regulated by legislation on the best available technologies. Mandatory requirements (technological parameters, BAT-AELs) are imposed, first of all, on the emissions limitation of inorganic dust, nitrogen and sulfur oxides. The majority of Russian cement plants are currently characterized by the nitrogen oxide emissions state-established technological indicators‘ excess. The technological indicators of the best available technologies and methods for reducing nitrogen oxide emissions operating in the Russian Federation and the EU countries are considered. It is demonstrated that the most efficient technologies are the staged fuel combustion and selective non-catalytic reduction (SNCR) of nitrogen oxides.

Modification of the structure of gypsum-cement-pozzolan binder allows you to expand the range of gypsum binders for creating dry building mixes and structural elements of low-rise buildings. It was found that in the presence of functional additives, the character of crystallization of hydrate neoplasms changes, which leads to a change in the properties of the hardened binder. The study of the effect of individual and complex additives on the properties of gypsum-cement-pozzolan binder allowed us to develop water-resistant gypsum binders.
