Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a geopolymer cured body capable of producing a geopolymer cured body on an industrial level by long taking a usable life even in a system utilizing blast furnace slag by performing a treatment of post-adding a silica component in the powder of silica fume.SOLUTION: In the method for producing a geopolymer cured body, by performing a treatment of stirring sodium hydroxide 1 and the powders of coal ash 2 and blast furnace slag 3 and thereafter gradually dissolving the powder of silica fume 4 as a silicon component, a setting time is gained, and a usable time is secured. 【課題】シリカ分をシリカヒュームの粉体で後添加する処理を行うことにより、高炉スラグを利用した系においても、可使時間を長くとれるようにすることにより、ジオポリマー硬化体の工業的レベルでの製造を可能とするジオポリマー硬化体の製造方法を提供する。【解決手段】ジオポリマー硬化体の製造方法において、水酸化ナトリウム１と石炭灰２・高炉スラグ３の粉体を攪拌した後、ケイ素分としてシリカヒューム４の粉体を徐々に溶かす処理をすることにより、凝結時間を稼ぎ、可使時間を確保する。【選択図】図１
