Method for producing cured geopolymer, cured geopolymer, method for producing geopolymer composition, and geopolymer composition
Provided is a method for producing a geopolymer cured product which is capable of preventing a decrease in fluidity of a geopolymer composition even when a large amount of blast furnace slag fine aggregate is used as the aggregate, and which has strong freeze-thaw resistance. This method for producing a geopolymer cured product is characterized by comprising: a first step for producing a geopolymer composition by kneading an aggregate comprising blast furnace slag fine aggregate, a powder comprising blast furnace slag fine powder, an alkali metal solution, gluconic acid, and water; and a second step for curing the geopolymer composition produced in the first step, in which the ratio (Si/M) of the amount of silicon (Si) contained in the geopolymer composition excluding the aggregate from the geopolymer composition to the amount of alkali metal (M) contained in the alkali metal solution is 1.6 < = Si/M < = 5.8, and the ratio (Si/M) of the amount of silicon (Si) contained in the geopolymer composition excluding the aggregate from the geopolymer composition to the amount of alkali metal (M) contained in the alkali metal solution is 1.6 < = Si/M < = 5.8. And the amount of substance per unit volume of the alkali metal contained in the geopolymer composition excluding the aggregate is 2.0 kmol/m3 or more.
