Abstract: Concrete 3D printing is a typical representative of modern digital manufacturing, which has attracted wide attention due to its technological advantages of intelligence, personalize and green construction. As a new construction method, concrete 3D printing has had a disruptive effect on the construction industry and has challenged traditional concrete materials. Improving the adaptability of concrete materials and 3D printing technology and realizing the wide application of 3D printing technology in buildings are the focus of general attention. In this paper, the development process of concrete 3D printing technology was summarized and the performance requirements of concrete materials for 3D printing were discussed, including the rheological properties, printability, buildability and mechanical properties. The typical application of 3D printing formwork technology in decoration and special-shaped structures was also introduced, which was expected to provide some reference for the research and engineering development of concrete 3D printing.

Key words: concrete, rheological property, 3D printing, 3D printing formwork, green construction
