Zusammenfassung:	Disclosed is a manufacturing method of a high strength geopolymer by recycling slag from a spent catalyst from a perspective of diversifying waste resources. The present invention provides the manufacturing method of a geopolymer, comprising: (a) a step of mixing slag from a spent catalyst, which comprises as main components, silica (SiO_2), alumina (Al_2O_3) and calcia (CaO), and an alkaline catalyst activator solution; (b) a step of curing the mixture; and (c) a step of aging the cured product. 폐자원 활용의 다양화 관점에서 폐촉매 슬래그를 재활용하여 고강도의 지오폴리머를 제조하는 방법이 개시된다. 본 발명은 (a) 실리카(SiO), 알루미나(AlO) 및 칼시아(CaO)를 주성분으로 하는 폐촉매 슬래그 및 알칼리 활성화제 용액을 혼합하는 단계; (b) 상기 혼합된 혼합물을 경화하는 단계; 및 (c) 및 상기 경화된 경화물을 재령하는 단계;를 포함하는 지오폴리머 제조방법을 제공한다.
