| 摘 要： | 通过对活性粉末混凝土材料进行Hopkinson压杆冲击压缩实验,得到不同钢纤维含量的活性粉末混凝土在不同应变率下的应力-应变全曲线,并给出了不同应变率下材料的动态压缩强度和动态增长因子,实验结果表明,活性粉末混凝土具有应变率敏感性,钢纤维的掺入部分提高了材料的冲击压缩性能。

| Abstract: | Impact compressive experiments on reactive powder concrete (RPC) were carried out using split Hopkinson pressure technique. With different steel-fiber contents and different dynamic increase factors (DIF), stress-strain curves, dynamic compressive strength at different strain-rates were obtained. Results show that RPC is strain-rate-dependent, and the introducing of steel-fiber improves the dynamic compressive strength of the RPC partly. |
