Zusammenfassung:To provide an environmentally friendly geopolymer molding formed from a curable composition of excellent reactivity, and having stable quality, high strength and high toughness.SOLUTION: The geopolymer molding is formed of a curable composition comprising at least one kind of aluminosilicate source (A), at least one kind of alkali metal silicate (B), and an alkali-resistant fiber (C), with the aluminosilicate source (A) with an SiOcontent of not less than 50 mass% based on the total mass of the aluminosilicate source (A) and an amorphous ratio of not less than 50 mass%, and including an aluminosilicate source with a mean particle diameter of not larger than 50 μm, a mean particle diameter of not larger than 10 μm, in an amount of not less than 30 mass% based on the total mass of the aluminosilicate source (A).SELECTED DRAWING: None 【課題】良好な反応性を有する硬化性組成物から形成され、安定した品質と、高強度および高靭性とを併せ持ち、環境にも優しいジオポリマー成形体を提供すること。【解決手段】(A)少なくとも一種のアルミノケイ酸塩源、(B)少なくとも一種のアルカリ金属ケイ酸塩および(C)耐アルカリ性繊維を含有する硬化性組成物から形成されるジオポリマー成形体であって、アルミノケイ酸塩源(A)は、SiO2含有量がアルミノケイ酸塩源(A)の総質量に基づいて50質量%以上であり、非晶質比率が50質量%以上であり、平均粒径が50μm以下であり、アルミノケイ酸塩源(A)の総質量に基づいて30質量%以上の、平均粒径が10μm以下であるアルミノケイ酸塩源を含む、成形体。【選択図】なし
