ABSTRACT

The article is devoted to the actual problem of processing of man-made waste generated by JSC “Gomel chemical plant”. One of the many types of tonnage of waste is phosphogypsum – waste production of wet-process phosphoric acid. The authors present the results of studies of artificial gypsum-based neutralized factological calcium sulphate – waste production of wet-process phosphoric acid by the hemihydrate method. On the basis of the experimental data revealed the possibility of replacing imported natural gypsum artificial stone on the basis of phosphopantothenate of calcium sulfate in the production of cement based on clinkers Belarusian cement plants and its impact on the hydration of clinker minerals. The authors consider the results of studies of another type of man-made waste generated by JSC “Gomel chemical plant” - silica gel, which is a waste of aluminum fluoride production. The limiting factor for its use is high humidity, which reaches 70 %. The article presents the results of studies on the basis of silica gel natural moisture sodium - or potassium-silicate binder, which is an analogue of liquid glass. The possibility of obtaining sodium - or potassium-silicate binder in a non-welding way, which can significantly reduce the energy consumption of the process by eliminating the stage of cooking silicate,which is mandatory in the traditional technology of producing liquid glass (sodium or potassium). The authors present the results of studies showing the possibility of obtaining on the basis of sodium - or potassium-silicate binder based on silica gel paint coatings for silicate bricks. Mineral pigments based on iron oxides: yellow iron oxide and red iron oxide and their combination were used as dyes in the research. It is established that the resulting coating is frost-and weather-resistant.

Keywords: artificial gypsum-based phosphopantothenate, cement, the silica gel, water glass, silicate bricks, paint coating.
