| summary |
In recent years, additive manufacturing and 3D printing technologies have been increasingly used in the field of construction engineering. 3D Concrete printing is a kind of laminated printing method using concrete extrusion technique. Concrete has the advantages of high compressive strength, low deformation, and excellent durability, and has high application value in the construction field. However, as a brittle material, concrete has limited tensile and flexural strength. For beam like components, it is difficult to fully exert the compressive performance of the material relying solely on itself, so it is difficult to apply to the bending member. The experimental case introduced in this paper combined the prestressing system with concrete printing technology. A post-tensioning prestressing system suitable for prefabricated concrete 3D printing components, which combined the excellent tensile properties of steel bars with the compressive performance of the 3D concrete printed part was proposed. |
