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 combinating these 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.
