3D打印纤维增强混凝土性能研究进展
Research Progress on the Properties of 3D Printing Fiber-reinforced Concrete
摘要
Abstract
3D printing-fiber reinforced concrete(3DP-FRC),as an important technology in the field of intelligent construction,has been widely applied in residential buildings,bridges,landscapes,and municipal engineering because of significant advantages in enhancing the customization of components,optimizing construction processes,and improving structural performance.The research progress of 3DP-FRC in terms of printability,mechanical prop-erties,and engineering applications are systematically reviewed.The effects of fiber type,size,and dosage on pumpability,extrudability,and buildability are comprehensively analyzed.Furthermore,combined with a micro-structural perspective,the influence of fiber orientation,interlayer bonding,and pore distribution on the mechani-cal anisotropy and interfacial performance of 3DP-FRC are explored.Combined with adaptability and enhancement mechanisms of many fiber systems(such as steel fibers,PVA fibers)during the printing,a collaborative optimization pathway integrating"fiber-printing process-micro structure-mechanical properties"is proposed,and the application potential of 3DP-FRC in complex structures,large-span components,and extreme environments are deeply dis-cussed.The findings highlight the promising prospects of 3DP-FRC in green construction,customized design,and functional-structural integration.Future research should focus on overcoming problems of fiber orientation control,interlayer bonding enhancement,and the lack of standard systems to advance 3DP-FRC toward more intelligent and engineering.关键词
