Abstract: The special construction technology of 3D printed concrete puts forward new requirements for concrete materials. The reasonable selection of the type and dosage of admixtures effectively adjusts the rheology, setting property, strength and durability of 3D printed concrete, and ensures the constructability and useability of 3D printed concrete. In this paper, the performance requirements of 3D printed concrete were firstly discussed, and then the action mechanism and usage of admixtures were analyzed, and theoretical suggestions for the selection of admixtures for 3D printed concrete were provided. At last, the future development of admixtures for 3D printed concrete were proposed.

Key words: 3D printed concrete, construction technology, admixture, rheology, setting property, strength, durability
