Abstract: Alkali-activated materials , as a new type of low-carbon building materials , have become one of the hot research fields with their excellent properties .The research progress in recent years in the structure composition and artificial synthesis methods of C-A-S-H and N-A-S-H in hydration products of alkali-activated materials are reviewed .The main methods of synthesizing C-A-S-H and N-A-S-H are sol-gel method , hydrothermal method and chemical precipitation method , and the synthesized C-A-S-H and N-A-S-H system products are also closely related to the synthesis methods .By summarizing the existing synthetic methods , the advantages and disadvantages of various synthetic methods are compared , and analyzed some problems to be solved in current research and future research directions .
