Abstract: Based on the most compact packing theory, the Funk-Dinger model was used and the quality of cementitious material was determined by Solver Tool in Microsoft Excel. The design of self-compacting ultra-high performance cement-based composites was achieved by adjusting q. The effects of synthetic-steel fiber hybridization on the uniaxial tensile properties of ultra-high performance cement-based composites were studied. The effects of steel-POM fiber hybrid and steel-PVA hybrid whole curve, there is a certain strain hardening phenomenon, with the increase of synthetic fiber content, the ultimate tensile strength increases and then decreases, the strain hardening process shorter. The effect of POM fiber and PVA fiber on the initial crack strength is different because of the different initial displacement and the different bond strength, so the phenomenon of strain hardening after adding PVA fiber is more obvious.
