摘 ? 要:研究了鋼渣微粉替代石英粉對超高性能混凝土(UHPC)性能的影響。結果表明:水膠比分別為0.18、0.19的UHPC試件的28 d抗壓強度均在120 MPa以上,且水膠比為0.19的UHPC的工作性更好,流動度為195 mm;鋼渣微粉替代石英粉對UHPC試件的抗壓強度無明顯影響;在鋼渣微粉摻量為100%的情況下,控制水膠比為0.20、水灰比為0.35、膠砂比為1.63時,可配制28 d抗壓強度為147.5 MPa的UHPC。
Abstract: The effect of steel slag powder instead of quartz powder on the properties of ultra-high performance concrete (UHPC) was studied. The results show that the 28 d compressive strength of UHPC specimens with water-binder ratio of 0.18 and 0.19 is more than 120 MPa, and the workability of UHPC with water-binder ratio of 0.19 is better and the fluidity is 195 mm. The substitution of steel slag powder for quartz powder has no obvious effect on the compressive strength of UHPC specimens. When the content of steel slag powder is 100%, the water-binder ratio is 0.20, the water-cement ratio is 0.35 and the binder-sand ratio is 1.63, and the 28 d compressive strength of UHPC can reach 147.5 MPa.
