| 摘 要： | 通过正交试验设计，采用粉煤灰代砂法掺入再生混凝土，并进行配合比设计。研究各材料用量与混凝土抗压强度之间的关系，利用线性回归分析推导出各材料用量与粉煤灰再生混凝土28d强度之间的定量关系。试验结果表明，线性回归分析显著，具有参考价值。

| Abstract: | In this paper, the writer chose the adding means of PFA replacing sand, and put forward the mix ratio design of concrete by orthogonal analysis experiments. What I studied was to made regression analysis and made out the linear relations between erery factors and the 28d strength of the PFA regenerated concrete. The experiment result is that the regression analysis is very remarkable and of reference value. |
