| 摘 要： | 采用正交试验设计方法对活性粉末混凝土（RPC）的配合比进行了试验设计，分别通过极差和方差分析了每个因素水平对RPC配合比的作用及各个水平之间的差异，探讨了水胶比、硅粉掺量、矿渣掺量对RPC各个基本力学性能影响的规律和机理。试验结果表明：水胶比与硅粉掺量对RPC抗压、抗折、劈裂抗拉有较为显著的影响；矿渣掺量对RPC各个强度影响均不显著。最后采用多元回归方法，建立了RPC强度与水胶比、硅粉掺量、矿渣掺量的经验公式，为RPC的进一步研究提供参考。

| Abstract: | Based on orthogonal experiment,the authors drafts an experimental design for the mix proportion of reactive powder concrete(RPC),analyzes different effect that produced by water-binger ratio,silica fume content or slag powder content on the mix proportion of RPC through extreme difference and variance analysis respectively,as well as studies the effect difference between the afore three factors,and probed into laws and mechanisms of water-binger ratio,silica fume content and slag powder content that affect ... |
