简介：反应粉末水泥(RPC)的三种类型的影响行为用测试方法的裂口Hopkinson出版社酒吧(SHPB)被学习。这些RPC分别地与0%，3%，和4%的钢纤维体积部分被准备。压力紧张关系，紧张率敏感阀值价值，动态力量增加因素，弹性的模量和使遭到影响负担的这些RPC标本的失败模式被调查。从测试，50s1的紧张率敏感阀值价值被获得。试验性的结果看了那紧张率什么时候从阀值价值增加了到RPC的最大的压力增加了大约20%的95s1,，RPC的弹性的模量增加了大约30%。当使遭到了影响时，有钢纤维加强的RPC标本的失败模式与RPC矩阵标本的很不同装载。在装载率的类似的影响下面，在钢纤维开发的裂缝增强了RPC标本，虽然RPC矩阵标本被分解为小片。

简介：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。
