Geopolymer cementing material for temporary spray anchor support engineering and preparation method of geopolymer cementing material
The invention relates to a geopolymer cementing material for temporary spray anchor support engineering and a preparation method of the material, the geopolymer cementing material is mainly prepared by mixing raw materials of low-calcium fly ash, granulated blast furnace slag powder and an alkali activator, the alkali activator is prepared by blending sodium silicate, sodium hydroxide or potassiumhydroxide and water, the molar ratio of M2O to SiO2 in the alkali activator is 0.50-0.78, and M represents Na or K. The invention also comprises a preparation method of the geopolymer cementing material. At normal temperature, the geopolymer cementing material disclosed by the invention can be quickly condensed and cured and can generate strength. The material provided by the invention is especially suitable for temporary slope support engineering and other similar cementing materials needing rapid strength acquisition, and has the advantages of early strength, rapid hardening, simple configuration, greenness and environmental protection.
