One-sack geopolymer compositions

A method of cementing, comprising:

• adding activator-free water to a dry geopolymer precursor composition comprising an aluminosilicate source and an activator to form a geopolymer slurry;
• pumping the geopolymer slurry to a cementing destination;
• and
• hardening the geopolymer slurry into a solid geopolymer at the cementing destination.

A method of cementing a subterranean well, comprising:

• mixing a dry geopolymer precursor, comprising an aluminosilicate source and an activator, with a non-activating water material to form a geopolymer slurry;
• pumping the geopolymer slurry into a subterranean well;
• and
• hardening the geopolymer slurry into a solid geopolymer within the subterranean well,
• wherein the aluminosilicate source is fly ash, volcanic ash, ground blast furnace slag, calcined or partially calcined clay, aluminum-containing silica fume, natural aluminosilicate, synthetic aluminosilicate glass powder, zeolite, scoria, allophone, bentonite, red mud, calcined red mud, pumice, or a combination thereof, and
• wherein the activator is a solid alkali metal silicate M2xSiyO2y+x where x is 1, 2, or 3 and y is 1 or 2, or a combination of thereof, or the activator is a mixture of an alkaline earth metal hydroxide, an alkaline earth metal oxide, an alkaline earth metal peroxide, or a combination of thereof with an alkali metal salt selected from the group consisting of M2CO3, M2SO4, M2SO3, M3PO4, M2C2O4, M2xSiyO2y+x where x is 1, 2, or 3 and y is 1 or 2, MF, M2SiF6, MIO3, M2MoO4, where M is, Li, Na, K, Rb, or Cs, or a combination thereof.

A method, comprising:

• mixing a dry geopolymer precursor, comprising an aluminosilicate source that is at least 18% by weight calcium oxide and a hydroxide-free activator, with a non-activating water material to form a geopolymer slurry;
• disposing the geopolymer slurry at a setting location;
• and
• hardening the geopolymer slurry into a solid geopolymer at the setting location.

A method, comprising:

• obtaining a dry geopolymer precursor comprising an aluminosilicate source and an activator;
• mixing the dry geopolymer precursor with a non-activating water material to form a geopolymer slurry;
• disposing the geopolymer slurry at a setting location;
• and
• hardening the geopolymer slurry into a solid geopolymer at the setting location.
