Abstract
This article studied the direct tensile properties of UHPC with different ratios and found that after reaching the maximum tensile load, the load gradually began to decrease and all showed a decrease in load fluctuations, with a certain strain hardening effect; As the crack width of the specimen increases, the load begins to steadily decrease. With the same ratio, as the cement strength increases, the initial cracking strength of UHPC increases by 65% and the tensile strength increases by 14%; The initial cracking strength of UHPC using cement from different origins did not change, but the tensile strength slightly increased; With the increase of fiber content, the initial cracking strength of UHPC increased by 39%, and there was no significant change in tensile strength.
