Abstract: 3D printed concrete has significant advantages in moldless and intelligent construction and has huge application potential. It has gradually become a rapidly rising research hotspot all over the world. At present, researchers at home and abroad have carried out research on its working and mechanical properties. The former mainly includes flowability, extrudability and buildability performance, while the latter mainly includes compressive strength, flexural strength and interlayer bond strength. Therefore, based on the current research status of 3D printed concrete at home and abroad, firstly, a specific review of its working properties and mechanical properties was carried out, with a focus on the research methods and research results obtained at this stage. Then, the main problems existing in the performance research and practical application of 3D printed concrete were summarized. At the same time, the current solutions were summarized and analyzed in view of the problems of low tensile strength and insufficient ductility. The future research direction was also pointed out, which could promote the research and application of 3D concrete printing technology.
