摘要：采用基于响应面法（RSM）的D-optimal最优化设计方法设计了超高性能混凝土（UHPC）净浆配合比，研究了复合胶凝材料组分对UHPC净浆湿堆积密实度、力学性能、干燥收缩性能的影响，结合XRD、SEM等微观测试结果分析了复合胶凝材料组分间的相互作用机理。结果表明：粉煤灰和硅灰可有效提高UHPC净浆的湿堆积密实度，优化基体内部颗粒堆积状态；硫铝酸盐水泥和粉煤灰对UHPC净浆的早期强度影响显著，掺入硫铝酸盐水泥可大幅提高UHPC净浆的早期力学性能。 Abstract: The D-optimal optimization design method based on response surface methodology(RSM) was used to design the slurry proportion of ultra-high performance concrete(UHPC). The influence of composite cementitious material components on wet packing density, mechanical properties, and drying shrinkage performance of UHPC slurry was studied, and the interaction mechanism between composite cementitious material components was analyzed by using XRD, SEM, and other microscopic test results. The results show that fly ash and silica fume can effectively improve the wet packing density of UHPC slurry and optimize the particle packing state inside the matrix. Sulfoaluminate cement and fly ash have a significant impact on the early strength of UHPC slurry. Adding sulfoaluminate cement can significantly improve the early mechanical properties of UHPC slurry.

The results show that fly ash and silica fume can effectively improve the wet packing density of UHPC slurry and optimize the particle packing state inside the matrix. Sulfoaluminate cement and fly ash have a significant impact on the early strength of UHPC slurry. Adding sulfoaluminate cement can significantly improve the early mechanical properties of UHPC slurry.
