Abstract Thermal curing and adding deformed steel fibers are effective in improving strength and toughness of UHPC. In this work, the effects of curing regime (28 d standard curing, 2 d of 90 ℃ steam curing, and 2 d of 90 ℃ hot water curing) and steel fiber shape (straight, corrugated, and hooked) on cubic compressive strength, uniaxial compressive strength, and flexural properties of UHPC were studied. ASTM C1018, JSCE-SF4, and modified Post-Crack-Energy Ratio (PCER) were used to evaluate the flexural toughness of UHPC. The 3D optical scanner was used to quantify the roughness of the fracture surface of UHPC with different steel fiber shapes. The results show that 2 d of hot water curing and steam curing improved the mechanical properties of UHPC to a certain extent, and the flexural properties of UHPC were significantly improved, in comparison to 28 d standard curing. Compared to UHPC with straight steel fibers, UHPC with hooked steel fibers increased the flexural strength and PCER toughness index by 46.26%—58.82% and 32.77%—39.81%, respectively, and enhanced the fracture surface roughness R_N by 41.67%. A good exponential relationship is found between roughness parameters and bending toughness, and the roughness parameter can be used to characterize the toughness of UHPC. Besides, a linear relationship between uniaxial compressive strength and cubic compressive strength was found, and the correlation coefficient ranged from 0.83 to 0.93. The toughness indexes evaluated using ASTM C1018 and PCER methods were basically consistent with the results obtained by using the area enclosed by load-displacement curve at 4 mm deflection and the flexural properties. The proposed modified PCER method introduced the initial flexural toughness ratio to characterize the flexural toughness before reaching the peak deflection, which rendered more accurate calculation results.
