| 摘 要： | 采用Φ100 mm分离式霍普金森压杆(SHPB)系统研究了玄武岩纤维增强地质聚合物混凝土(BFRGC)的高应变率力学行为，包括抗压强度、变形及能量吸收特性的应变率效应问题。结果表明：地质聚合物混凝土材料的高应变率力学性能呈现出显著的应变率相关性；BFRGC的强度特性相对于地质聚合物混凝土(GC)无明显改善，而变形及能量吸收能力较 GC有明显提高。 |

| Abstract: | The high-strain-rate mechanical behavior of the basalt fiber reinforced geopolymeric concrete(BFRGC),including compressive strength,deformation and energy absorption capacities,was investigated using a 100 mm-diameter split Hopkinson pressure bar(SHPB).The experimental results show that the high-strain-rate behavior of geopolymeric concrete materials exhibits strong strain rate dependency.The addition of short basalt fibers can significantly improve the deformation and energy absorption capacities of the ge... |
| Keywords: | basalt fiber reinforced geopolymeric concrete (BFRGC) split Hopkinson pressure bar (SHPB) strain rate effect mechanical behavior |
