Summary:To provide a geopolymer composition having good fresh properties and excellent initial strength.SOLUTION: A geopolymer composition includes an inorganic filler, and an alkali silicate aqueous solution including at least one member selected from the group consisting of sodium and potassium, a retardant, a water reducing agent, and an antifoaming agent, wherein the inorganic filler contains fly ash and blast furnace slag powder, a ratio of the blast furnace slag powder to the total inorganic filler is 45 to 90 mass%, a blending ratio of the retardant to the total inorganic filler is 0.1 to 1.9 mass%, and a ratio of the water reducing agent to the total inorganic filler is greater than 0.2 mass% and equal to or less than 1.0 mass%.SELECTED DRAWING: None 【課題】良好なフレッシュ性状を有しつつ初期強度にも優れるジオポリマー組成物を提供すること。【解決手段】無機フィラー、ナトリウム及びカリウムからなる群より選ばれる少なくとも一つを含むケイ酸アルカリ水溶液、遅延剤、減水剤、並びに消泡剤を含み、無機フィラーは、フライアッシュ及び高炉スラグ微粉末を含み、無機フィラー全体に対する高炉スラグ微粉末の比率は４５～９０質量％であり、無機フィラー全体に対する遅延剤の配合比率は０．１～１．９質量％であり、無機フィラー全体に対する減水剤の配合比率は０．２質量％より大きく１．０質量％以下である、ジオポリマー組成物を提供する。【選択図】なし
