  • In order to overcome the defects of Portland cement with its high energy consumption, high pollution and high CO2 emission, it has reached a consensus on the development of new low-carbon cementing materials that can replace Portland cement. In this paper, composite geopolymer cement (CGC) was prepared by using alkaline solution to activate multi-componental aluminum silicates under normal conditions. Based on the molar ratio of key oxides and geopolymeric reaction mechanism, the mixture proportions of CGC were designed. The effects of key parameters including precursor, alkali activator, water-solid ratio, curing medium on compressive strength of CGC were discussed. The results showed that the prepared CGC under normal conditions met the usage requirements well. When the contents of slag and metakaolin in the precursor were higher, the strength of CGC was greater. When the content of fly ash was higher, the strength of CGC was lower. The relation between CGC's strength and the contents of water glass and NaOH was non-monotonic. The strength of CGC specimens immersed in artificial seawater was nearly 7% lower than the one stored in standard conditions.
