Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a geopolymer composition expressing a set compression strength, and a method for production thereof.SOLUTION: A geopolymer composition is produced by kneading, curing and hardening the mixture of: a filler composed of fly ash and a blast furnace slag; an alkali solution; and an aggregate. The composition contains a sodium amount different from that of the stoichiometric composition of water glass. In the inner percentage replacement ratio of the fly ash and the blast furnace slag in response to the set compression strength of the geopolymer composition, the blast furnace slag is made to be 10% or more of the fly ash.SELECTED DRAWING: Figure 6 【課題】設定した圧縮強度を発現するジオポリマー組成物およびその製造方法を提供する。【解決手段】ジオポリマー組成物は、フライアッシュと高炉スラグとから構成されるフィラーと、アルカリ溶液と、骨材とを混練し、養生して硬化させることにより製造され、ジオポリマー組成物が水ガラスの量論組成と異なる量のナトリウムを含有する。また、本発明のジオポリマー組成物は、設定される圧縮強度に応じてフライアッシュと高炉スラグとの内割り置換率において、前記高炉スラグが前記フライアッシュの１０％以上とすることができる。【選択図】図６
