inorganic binder systems for the production of construction chemicals chemically resistant

An inorganic binder system comprising from 10 to 30 parts by weight of at least one latent hydraulic binder selected from blast furnace slag, slag sand, crushed slag, slag electrothermal phosphorus and steel slag, from 5 to 22 parts by weight at least one amorphous silica selected from precipitated silica, fumed silica, microsilica and glass powder, from 0 to 15 parts by weight of at least one reactive filler selected from lignite fly ash, fly ash mineral coal, metakaolin, volcanic ash , tuff, trass, pozzolana and zeolites, and from 3 to 20 parts by weight of at least one alkali metal silicate selected from compounds having the empirical formula m SiO2 · n M2O, wherein m represents Li, Na, K or NH4, or a mixture thereof, preferably Na or K, and the molar ratio of m: n is <= 3.6, preferably <= 3.0, more preferably <= 2.0, especially <= 1, 70 and most preferably <= 1.20 in d onde the binder system comprises from 12 to 25% by weight of CaO, where required 10 to 50 parts by weight, preferably 20 to 40 parts by weight of water for the setting, and wherein the hydraulic binder latent, the amorphous silica and the optional reactive filler present as a first component and the alkali metal silicate together with at least the amount of water required for the setting are present as a second component.
