摘要：基于最大湿堆积密度理论优化设计超高性能混凝土（UHPC）。首先，设计了25组试验工况，分别计算出每组工况变量与最大湿堆积密度的关系，建立了最大湿堆积密度预测模型。然后，用石英粉部分替代水泥，研究了不同替代率对UHPC流动性、力学性能的影响。结果表明：预测模型与试验结果具有较好的吻合性；UHPC的流动度随着石英粉掺量的增加而增加，且当石英粉掺量为20%时，UHPC的抗压强度和抗折强度最大。此外，生态评价表明，使用石英粉部分替代水泥生产UHPC，可显著降低对环境的影响。 Abstract: Mix proportion of ultra-high performance concrete (UHPC) was optimal designed based on maximum wet packing density theory. Firstly, 25 groups of test conditions were designed, the relationship between each working condition variable and the maximum wet packing density was calculated, and the prediction model of the maximum wet packing density was established. Then, quartz powder was used to partially replace cement, and the effects of different substitution rates on the fluidity and mechanical properties of UHPC were studied. The results show that the prediction model is in good agreement with the experimental results. The fluidity of UHPC increases with the increase of quartz powder content. When the content of quartz powder is 20%, the compressive strength and flexural strength of UHPC are the largest. In addition, the ecological evaluation shows that using quartz powder to partially replace cement to produce UHPC can significantly reduce the impact on the environment.
