In order to explore the influence of material composition on the mechanical properties of ultra-high performance strain-hardened cementitious composites,UHP-SHCC was prepared by orthogonal test with silica fume content,slag content and sand-glue ratio as influencing factors,and its mechanical properties were comprehensively analyzed.The results show that the silica fume content has a great influence on its compressive strength,initial cracking strength and tensile strength,and the sand-glue ratio has a great influence on its ultimate tensile strain.In the case of silica fume content of 30%,slag content of 15%,sand glue ratio of 0.4,PE fiber content of 2%,and water-glue ratio of 0.16,its comprehensive mechanical properties are better.
