As a new type of green building material, alkali-activated material has outstanding advantages in many fields, such as recycling of industrial solid wastes and reduction of CO₂ emission. In recent years, more and more attention has been paid to durability of this material. Carbonation as a key factor affecting durability also needs further research. From the aspects of carbonation mechanism, carbonation rate, carbonation effect and improvement of carbonation resistance, this paper summarizes the research status of carbonation performance of alkali-activated materials and achievements and difficulties in this field. Based on the existing results, some research suggestions are proposed to provide reference for the development and application of alkaliactivated concrete.
