Fly ash based alkali-activated material and geopolymer were synthesized at 80℃ to study the reaction system of alkali activated condition and the system with/without liquid glass. X-ray diffraction and 29Si NMR were obtained to discuss the role of Si in those systems. Liquid glass always produced a reactant having a three-dimensional network. Physical properties are also obtained to discuss the applicability of those materials. As a result, fly ash based system containing the mixture of NaOH solution and liquid glass solution showed high potential for engineering applications.
