A Fundamental Study Progress on Reinforcement Enhancement of 3D Printed Concrete
3D printed concrete(3DPC)has been the subject of ongoing study in recent years due to the growing trend of intelligent building materials industry and construction industry.Due to the automation,intelligent,and formwork-free advantages,several engineering demonstrations have been established.There are more demands on 3DPC properties because of its widespread application in engineering.Engineering applications are also placing greater demands on the performance of 3DPC which requiring selective reinforcement enhancements for safe and reliability design.3DPC reinforcement technology is different from casting concrete construction due to the changing preparation process.And scientific optimization and performance control should be carried out for the reinforcement method under printing.This paper focuses on the development of 3DPC reinforcement enhancement study in terms of the reinforcing process,materials and features,numerical analysis,and comprehensive microscopic characterization.In addition,the challenges faced by reinforcement enhancement fundamental research and the technical difficulties of future development are also briefly discussed.The intention is to serve as a reference for the scientific development of reinforced 3DPC structures,meeting the demand for safe applications guidance.
