Mechanical Properties of 3D Printed Concrete Reinforced by Embedding Multi-Cables
连续微筋同步增强方法满足混凝土 3D打印技术灵活性的要求,可有效提高3D打印混凝土结构的强度和延性.为进一步提高3D打印混凝土结构的承载能力,提出3D打印混凝土多筋同步增强方法.优化多筋同步置入工艺,开展微筋拉拔试验,研究多筋与基体间粘结特性.研究配筋率对抗弯性能的影响,并建立多筋增强3D打印混凝土梁在弯曲作用下的截面承载力计算公式.结果表明,微筋的拔出损伤基体材料,进而降低剩余微筋与基体间粘结强度,且下降幅度随微筋间距减小而增大,微筋间距减小到…查看全部>>
The synchronous strengthening method of continuous micro-cable meets the flexibility requirements of 3 D printing technology of concrete and can effectively improve the strength and ductility of 3D printed concrete structures.To further improve the bearing capacity of 3D printed concrete structures,a synchronous multi-cables reinforcement method of 3D printed concrete was proposed.Optimizing the multi-cables synchronous embedding process,pull-out tests…查看全部>>
