Abstract:
In order to comprehensively analyze the research status of 3D printed concrete technology in China, the research progress of 3D printed concrete technology from the aspects of ink materials, construction technology and application scenarios was reviewed, and the development process of the technology was analyzed from two aspects of time and logic. The main construction technology and application cases in buildings and infrastructures were introduced. The development trend of 3D printed concrete technology in ecological ink materials, bionic design, large-scale printing equipment development and construction technology, and 3D printed concrete technical standards and acceptance specifications were analyzed. Finally, the problems of 3D printed concrete technology in China were analyzed and summarized, and some research ideas were given combined with practical application scenarios. The results show that 3D printed material is the most fundamental factor affecting the performance of concrete. Concrete must have better rheological properties and be able to set rapidly in the environment. The existing 3D printed concrete equipment can not fully meet the special requirements of different application environments. It is necessary to coordinate the development of mechanical design and construction process, so as to promote the refinement and automation development of new 3D printing equipment in the construction field. 3D printed concrete structure is different from ordinary concrete structure, so the existing concrete structure design and construction standards and national regulations are not suitable for 3D printed concrete technology, lacking standards and acceptance specifications for 3D printed buildings. Enterprises, universities and scientific research institutions need to strengthen cooperation to guide the research and development of 3D printed concrete oriented by the engineering application.
