The potential utilization of slags from the secondary metallurgy
Original language description
Significant raw materials for potential utilization at geopolymer binders' preparation are slags from steel production, in the first place ladle slag. According to the kind of produced steel the composition of these products in simplified systém of maincomponents comes under the two zones. Bigger part comprises slags with 15 - 40% SiO2 and 55 - 80% CaO, which show latent hydraulicity. With their activating by the water glass influence one gains binders of very good strength parameters. When combinatingthese slags with granulated blast furnace slag (GBFS) and fly ash (FA), can be modified not only the processability of mixtures, setting and hardening course but also the prise level of the products. Examples of strength development of specific raw materials mixtures from our region activated with water glass solution - silicate module SM= 2,0 and low Na2O dose are in the fig. 2. These and other hardened masses show exceptionally good corrosion resistance in distilled water, acid and sa

Potenciální využití strusek ze sekundární metalurgie
Czech description
Významnou surovinou pro přípravu geopolymerních pojiv mohou být strusky ze sekundární metalurgie, zvláště strusky pánvové. Jejich složení je předpokladem pro jejich latentní hydraulicitu. Aktivací roztoky vodního skla jak samotné, tak v kombinaci s granulovanou vysokopecní struskou a nebo popílkem poskytují pojiva vysokých pevností a velmi dobré korozní odolnosti. Využívání uvedených surovin by přineslo ekonomické i ekologické výhody.
