摘   要:研究了矿渣粉掺量、硅灰掺量、钢纤维掺量和水胶比对超高性能混凝土(UHPC)工作性和力学性能的影响,并通过显著性分析探讨了各因素对UHPC性能的影响程度。结果表明:随着矿渣粉掺量的增加,UHPC的扩展度和28 d抗压、抗折强度均先增大后减小;随着硅灰掺量的增加,UHPC的扩展度和28 d抗压、抗折强度基本呈先增大后减小的趋势;随着钢纤维掺量的增加,UHPC的扩展度降低,28 d抗压、抗折强度增大;随着水胶比的增加,UHPC的扩展度增大,28 d抗压、抗折强度先增大后减小;钢纤维掺量对UHPC力学性能的影响程度最大,水胶比对UHPC工作性的影响程度最大;综合考虑工作性和力学性能,自密实UHPC的最佳配合比为矿渣粉掺量20%、硅灰掺量12%、钢纤维掺量2.0%、水胶比0.18。 Abstract: The effects of slag powder content, silica fume content, steel fiber content and water-cement ratio on the workability and mechanical properties of ultra-high performance concrete(UHPC) were studied, and the degree of influence of various factors on the performance of UHPC was explored through significance analysis. The results show that with the increase of slag powder content, the slump-flow and 28 d compressive and flexural strength of UHPC first increase and then decrease. With the increase of silica fume content, the slump-flow and 28 d compressive and flexural strength of UHPC show a trend of first increasing and then decreasing. With the increase of steel fiber content, the slump-flow of UHPC decreases, and the 28 d compressive and flexural strength of UHPC increase. As the water-cement ratio increases, the slump-flow of UHPC increases, and the 28 d compressive and flexural strength first increase and then decrease. The steel fiber content has the greatest impact on the mechanical properties of UHPC, and the water-cement ratio has the greatest impact on the workability of UHPC. Taking into account workability and mechanical properties, the optimal mix proportion of self compacting UHPC is 20% content of slag powder, 12% content of silica fume, 2.0% content of steel fiber and 0.18 of water-cement ratio.

Abstract: The effects of slag powder content, silica fume content, steel fiber content and water-cement ratio on the workability and mechanical properties of ultra-high performance concrete(UHPC) were studied, and the degree of influence of various factors on the performance of UHPC was explored through significance analysis. The results show that with the increase of slag powder content, the slump-flow and 28 d compressive and flexural strength of UHPC first increase and then decrease. With the increase of silica fume content, the slump-flow and 28 d compressive and flexural strength of UHPC show a trend of first increasing and then decreasing. With the increase of steel fiber content, the slump-flow of UHPC decreases, and the 28 d compressive and flexural strength of UHPC increase. As the water-cement ratio increases, the slump-flow of UHPC increases, and the 28 d compressive and flexural strength first increase and then decrease. The steel fiber content has the greatest impact on the mechanical properties of UHPC, and the water-cement ratio has the greatest impact on the workability of UHPC. Taking into account workability and mechanical properties, the optimal mix proportion of self compacting UHPC is 20% content of slag powder, 12% content of silica fume, 2.0% content of steel fiber and 0.18 of water-cement ratio.

(1)随着矿渣粉掺量的增加,UHPC的扩展度和各龄期的抗压、抗折强度均先增大后减小,综合考虑工作性和力学性能,矿渣粉的最佳掺量为20%。
(2)随着硅灰掺量的增加,UHPC的扩展度和各龄期的抗压、抗折强度基本呈先增大后减小的趋势,综合考虑工作性和力学性能,硅灰的最佳掺量为12%。
(3)随着钢纤维掺量的增加,UHPC的扩展度降低,各龄期的抗压、抗折强度均增大,综合考虑成本、UHPC的力学性能和工作性,钢纤维的最佳掺量为2.0%。
(4)随着水胶比的增加,UHPC的扩展度增大,各龄期的抗压、抗折强度均先增大后减小,综合考虑工作性和力学性能,最佳水胶比为0.18。
(5)显著性分析结果表明,各因素对UHPC力学性能的影响程度大小顺序为:钢纤维掺量>硅灰掺量>矿渣粉掺量>水胶比;各因素对UHPC工作性的影响程度大小顺序为:水胶比>钢纤维掺量>矿渣粉掺量>硅灰掺量。
