The present invention relates to a geopolymer composition capable of preventing a drastic decrease in workability (for example, iron separation) at the time of kneading while ensuring a practical blend in which fly ash-based geopolymer is improved in strength with blast furnace slag. We provide mortar or concrete or secondary concrete products using A geopolymer composition produced by kneading, curing, and curing a filler composed of fly ash and blast furnace slag, an alkaline solution, and an aggregate, the fly as filler Part of the ash is further replaced with a certain amount of silica fume to adjust the particle size.
