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.
