Ultra-high performance concrete (UHPC) was designed with different replacement percentages of manufactured sand, i.e., 0%, 25% 50%, 75%, and 100% (in mass fraction). The properties of the UHPC, including the quasi static and dynamic mechanical properties, were examined. The results show that the compressive strength of UHPCs with manufactured sand as fine aggregates is similar to that of the reference mixture with only river sand. The UHPC with manufactured sand has superior dynamic mechanical properties. The UHPC with manufactured sand has an effect on its strain rate, and the dynamic increase factor has a logarithmic function relation with the strain rate. In addition, the finite element method was also employed to simulate the impact process of the UHPC with manufactured sand.

采用机制砂等质量替代河砂用于制备超高性能混凝土(UHPC),替代率分别为0%,25%,50%,75%以及100%,研究了机制砂对UHPC动静态力学性能的影响。结果表明:机制砂替代河砂后,所制备的UHPC抗压强度与仅用河砂配制的UHPC抗压强度相近;机制砂UHPC具有优异的抗冲击性能,可以承受多次冲击行为,此外机制砂UHPC具有明显的应变率效应,动态增强因子DIF与应变率呈对数函数关系。采用有限元法(LS-DYNA)模拟了机制砂UHPC的冲击过程,数值模拟结果表明应力应变曲线和破坏形态均与试验较为吻合。

采用机制砂等质量替代河砂用于制备超高性能混凝土(UHPC),替代率分别为0%,25%,50%,75%以及100%,研究了机制砂对UHPC动静态力学性能的影响。结果表明:机制砂替代河砂后,所制备的UHPC抗压强度与仅用河砂配制的UHPC抗压强度相近;机制砂UHPC具有优异的抗冲击性能,可以承受多次冲击行为,此外机制砂UHPC具有明显的应变率效应,动态增强因子DIF与应变率呈对数函数关系。采用有限元法(LS-DYNA)模拟了机制砂UHPC的冲击过程,数值模拟结果表明应力应变曲线和破坏形态均与试验较为吻合。

Ultra-high performance concrete (UHPC) was designed with different replacement percentages of manufactured sand, i.e., 0%, 25% 50%, 75%, and 100% (in mass fraction). The properties of the UHPC, including the quasi static and dynamic mechanical properties, were examined. The results show that the compressive strength of UHPCs with manufactured sand as fine aggregates is similar to that of the reference mixture with only river sand. The UHPC with manufactured sand has superior dynamic mechanical properties. The UHPC with manufactured sand has an effect on its strain rate, and the dynamic increase factor has a logarithmic function relation with the strain rate. In addition, the finite element method was also employed to simulate the impact process of the UHPC with manufactured sand.
