Summary:To provide: a geopolymer composition having improved on-site workability; a method for producing the geopolymer composition; and a method for producing a geopolymer-hardened body.SOLUTION: A geopolymer composition comprises a fly ash, a slag, a fine aggregate, an alkali metal hydroxide, and water. The geopolymer composition is derived from an alkali metal hydroxide solution in which: a total content of the alkali metal hydroxide and the water is 10 to 70 pts.mass based on 100 pts.mass of a total mass of the fly ash and the slag; and a concentration of a total amount of the alkali metal hydroxide is 5 g/100 mL or less.SELECTED DRAWING: None 【課題】現場での施工性が改善された、ジオポリマー組成物、ジオポリマー組成物の製造方法及びジオポリマー硬化体の製造方法の提供。【解決手段】フライアッシュと、スラグと、細骨材と、アルカリ金属水酸化物と、水と、を含むジオポリマー組成物であって、前記アルカリ金属水酸化物及び前記水の合計含有量が、前記フライアッシュ及び前記スラグの合計質量１００質量部に対して、１０〜７０質量部であり、前記アルカリ金属水酸化物の全量は５ｇ／１００ｍＬ以下の濃度のアルカリ金属水酸化物水溶液に由来する、ジオポリマー組成物。【選択図】なし
