dc.description.abstract | 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. © 2021 Elsevier Ltd | - |
