Alkali-activated cementing material doped with high-silicon iron tailings and lime and preparation method of alkali-activated cementing material
The invention relates to an alkali-activated cementing material doped with high-silicon iron tailings and lime, which belongs to the field of alkali-activated inorganic nonmetal cementing materials. The invention relates to an alkali-activated cementing material doped with high-silicon iron tailings and lime. The alkali-activated cementing material is prepared from the following raw materials: high-silicon iron tailings, lime, alkaline residues, blast furnace slag and an alkali activator. The raw materials comprise, by mass, 30-50 parts of high-silicon iron tailings, 15-20 parts of lime, 20-40 parts of blast furnace slag, 5-10 parts of alkaline residues, and 1-5 parts of an alkaline activator; and the alkali activator is a solution prepared by mixing NaOH and Na2SiO3. According to the alkali-activated cementing material doped with the high-silicon iron tailings and the lime, the solid waste and the lime generated after mining of an iron ore plant are mainly utilized, the purpose of the alkali-activated cementing material can be achieved by doping a proper amount of the high-silicon iron tailings and the lime, and secondary utilization of the high-silicon iron tailings is achieved.
