SYSTEM OF INORGANIC BINDING SUBSTANCE FOR OBTAINING CHEMICALLY STABLE BUILDING CHEMICAL PRODUCTS Russian patent published in 2015 - IPC C04B7/153 C04B12/04 C04B28/08 C04B28/26 C04B111/20 

FIELD: chemistry.

SUBSTANCE: invention relates to inorganic binding agents. System of inorganic binding agent includes, wt.p.: 10-30 of at least one latent hydraulic binding substance, selected from blast furnace slag, slag sand, milled slag, electrothermal phosphorus slag and metal-containing slag, 5-22 of at least one amorphous silicon dioxide, selected from precipitated silicon dioxide, pyrogenic silicon dioxide, microsilica and glass powder, 0-15 of at least one reactionable filler, selected from brown coal fly ash, mineral coal fly ash, metakaolin, volcanic ash, tuff, trass, pozzolan and zeolites, and 3-20 of at least one alkali metal silicate, and in which content of CaO is 12-25 wt %, setting requires 10-50 wt.p., latent hydraulic binding substance, amorphous silicon dioxide and optional said filler is present as first component and alkali metal silicate and water - as second component. System can be applied for obtaining hydraulically setting mortar.

EFFECT: increased resistance to action of acid, water and alkali.
