Effects of coarse aggregate content and particle size on mechanical properties of ultra-high performance concrete (UHPC) with river sand as a coarse aggregate replacing quartz sand were investigated. The results show that the cube compressive strength and axial compressive strength of UHPC matrix are obtained at the coarse aggregate filling content of less than 400 kg/m3. The cube compressive strength and axial compressive strength decrease when the filling content of coarse aggregate further increases. The increase of particle size of coarse aggregate has a strengthening effect on the cube compressive strength and axial compressive strength of UHPC matrix, while the particle size of coarse aggregate has little effect on the UHPC flexural and splitting tensile strength. The UHPC initial crack strength, peak strength, initial crack deflection, peak deflection and energy dissipation decrease slowly with the increase of coarse aggregate filling content. The strength and energy dissipation in each stage decrease with the increase of particle size of coarse aggregate, while the initial crack deflection and peak deflection have a slow increasing trend with the increase of particle size of coarse aggregate, and the toughness index decreases gradually with the increase of aggregate filling content and particle size.
