A comprehensive study of the composition, structure and properties of microsilica from the sludge field of JSC Kremniy was conducted. It was shown that the capture of microsilica during gas purification with a soda solution and its storage under a layer of water on the sludge field for many years contributed to the formation of agglomerates of particles with an average size of 7-16 μm, consisting of nanosized amorphous silica particles of spherical shape. It was found that microsilica has a relatively low pozzolanic activity, and agglomerates of its particles formed during capture during gas purification and long-term storage on the sludge field reduce the efficiency of using microsilica as an active mineral additive. To increase the activity of microsilica and destroy agglomerates, intensive mechanical action is required during the processing of microsilica as part of various building materials. The laboratory studies have confirmed the possibility of using microsilica in the construction industry as an active mineral additive to cements, including as a substitute for part of the clinker, as an "acidic" component of unfired hydraulic and autoclave hardening binder, and as a silica-containing additive to raw sludge for clinker firing. It has been shown that the use of microsilica from JSC "Kremniy" in the construction industry will improve the environmental situation in the region, and the experience of using waste described in the work can be extended to other metallurgical enterprises.
