中文摘要：

裂口 Hopkinson 压力酒吧(SHPB ) 技术被用来与不同钢纤维内容决定反应粉末水泥(RPC ) 的动态力量。有不同厚度的脉搏 shapers 的二种类型被认为减少 high-frequency-oscillation 效果并且在某个变丑范围上完成将近经常的紧张率。像水泥的材料的压缩力量是 hydrostatic-stress-dependent，这被知道，并且明显的动态力量改进来自两个静水力学的压力和紧张的效果评价。以便区分他们，数字方法被用来在 RPC 的动态压缩强度上计算静水力学的应力，然后真紧张率效果的贡献被决定。另外，动态力量和 RPC 的失败模式上的钢纤维的效果被讨论。

英文摘要：

Split Hopkinson pressure bar （SHPB） technique is used to determine the dynamic strength of reactive powder concretes （RPCs） with different steel-fiber contents. Two types of pulse shapers with different thicknesses are considered to reduce the high-frequency-oscillation effect and achieve a nearly constant strain rate over a certain deformation range. It is known that the compressive strength of concrete-like materials is hydrostatic-stress-dependent, and the apparent dynamic strength enhancement comes from both the effects of the hydrostatic stress and strain rate. In order to differentiate them, numerical method is used to calculate the contribution of the hydrostatic stress, and then the genuine strain-rate effect on dynamic compressive strength of RPCs is determined. In addition, the effect of steel-fibers on dynamic strength and failure mode of RPCs is discussed.
