摘 要:研究了钢渣微粉替代石英粉对超高性能混凝土(UHPC)性能的影响。结果表明:水胶比分别为0.18、0.19的UHPC试件的28 d抗压强度均在120 MPa以上,且水胶比为0.19的UHPC的工作性更好,流动度为195 mm;钢渣微粉替代石英粉对UHPC试件的抗压强度无明显影响;在钢渣微粉掺量为100%的情况下,控制水胶比为0.20、水灰比为0.35、胶砂比为1.63时,可配制28 d抗压强度为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.
