To study the effect of different slag content and different curing methods on the carbonation resistance of fly ash- and slag-based geopolymer concrete (FA&SL-GPC), a series of experiments were carried out with slag content (accounting for 10%, 30% and 50% of cementitious materials) and curing methods (standard curing and high temperature curing) as variables. The results show that increasing the slag content is helpful for improving the carbonation resistance properties, microstructure, and carbonation resistance components of FA&SL-GPC substrate. Adopting a standard curing method and prolonging the curing age are more favorable to the carbonation resistance of FA&SL-GPC, and the longer the curing time is, the better. Finally, the carbonation depth prediction model suitable for this experiment is deduced and verified. From the research results, it can be seen that using a high slag content mix and curing under standard conditions is beneficial for the carbonization resistance of GPC structural components.
