Study on the Shear Key-shaped Mold making Method utilizing 3D Printers

Due to the construction of high-rise and long axis etc, UHPC(Ultra High Performance Concrete) has attracted attention as a material that will replace the existing concrete. In order to improve the structural performance of each member joints, after demolding the concrete, method for surface treatment of the contact surface or by modifying the mold to create a shear key will be applied. In this study, to improve the conventional shear key manufacturing process, utilizing a 3d printer to produce a shear key plate. 3D printers have advantage it is inexpensively manufactured as compared with other production methods. Therefore, this study utilizes a 3D printer, we propose the shear key-shaped mold and plate shear key production measures.
