摘要：利用正交实验、Dinger-Funk连续分布理论等进行活性粉末混凝土（RPC）配合比设计，探究了不同配合比设计方法所制备的活性粉末混凝土的物理力学性能。研究结果表明，活性粉末混凝土的力学性能是物理堆积和化学反应的共同作用，单纯利用紧密堆积原理无法制备出高强度的活性粉末混凝土；对惰性材料含量较多的多组分材料应用Dinger-Funk连续分布理论，很难制备出力学性能优异的RPC材料；利用石英砂的紧密堆积+粉体材料的Dinger-Funk连续分布理论模型，再控制适当的砂胶比，可以配制出力学性能更优的活性粉末混凝土；影响RPC抗折强度和抗压强度的因素不同，RPC抗折强度和抗压强度不存在正相关的关系。 Abstract: Orthogonal design, Dinger-Funk continuous distribution theory were used to design the mix proportion of reactive powder concrete (RPC), and the compressive and flexural strength of reactive powder concrete under different mix design methods were explored. The results show that the mechanical properties of reactive powder concrete are a combination of physical accumulation and chemical reaction. Simply using the principle of the most closely packed cannot be prepared high strength of the reactive powder concrete. The Dinger-Funk continuous distribution model of multi-component materials with high content of inert material is difficult to prepare RPC material with excellent mechanical properties. The most compact accumulation of quartz sand and the Dinger-Funk equation continuous distribution model of mineral admixture can be used to construct the reactive powder concrete with better mechanical properties. There is no positive correlation between the flexural strength and compressive strength of reactive powder concrete.
