MANUFACTURING METHOD OF GEOPOLYMER HAVING HIGH STRENGTH BY USING COAL GASIFICATION SLAG

摘要

Disclosed is a method for manufacturing a high strength geopolymer by recycling coal gasification slag in various aspects of using waste resources. Provided in the present invention is the method for manufacturing a geopolymer, comprising the following steps: (a) mixing coal gasification slag (CGS) having silica (SiO_2) and alumina (Al_2O_3) as main components, and an alkali activating solution; (b) curing the mixture; and (c) aging the cured product.
