The drop-weight impact behavior of the ductility enhanced high-strength strain-hardening cementitious composites (dHS-SHCC) is compared to that of conventional reactive powder concrete (RPC) to validate its super-impact resistance. All materials have an identical fiber volume fraction of 2%. The compressive strengths of RPC and dHS-SHCC are approximately 210 and 115 MPa, respectively. RPC has the highest ultimate tensile strength of 17.9 MPa, while the developed dHS-SHCC has the highest tensile strain capacity and energy absorption capacity up to the peak ($g$-value) of 5.9% and 526.0 kJ/m³, respectively. It also absorbs 3.2 times higher energy up to the peak under flexure (toughness) as compared to that of RPC. The RPC beams completely fail upon impact of a drop hammer with a potential energy of 490 J. However, the dHS-SHCC beams are only partially damaged along with multiple microcrack formations and rebounds. Moreover, it produces at least four times the microcracks and is more sensitive to the strain-rate than those of RPC. Consequently, it can be determined that using developed dHS-SHCC is effective in resisting impact loads as compared to RPC.

将延展性增强的高强度应变硬化水泥基复合材料（dHS-SHCC）与常规反应性粉末混凝土（RPC）的跌落冲击行为进行了比较，以验证其超抗冲击性。所有材料的纤维体积分数相同，均为2％。的压缩强度RPC和DHS-SHCC的是大约210和115兆帕，分别。RPC的最高极限抗拉强度为17.9 MPa，而发达的dHS-SHCC则具有最高的拉伸应变能力和能量吸收能力，最高可达峰值（$G$值）分别为5.9％和526.0 kJ / m ³ 。与RPC相比，它在弯曲（韧性）下的峰值处吸收的能量也高3.2倍。RPC梁在落锤的冲击下完全失效，势能为490J。但是，dHS-SHCC梁仅被部分损坏，并形成了多个微裂纹和回弹。此外，它产生的微裂纹至少是RPC的四倍，并且对应变率更敏感。因此，可以确定，与RPC相比，使用开发的dHS-SHCC可有效抵抗冲击载荷。
