摘要
运用灰色关联分析的方法考察了影响再生混凝土砌块抗压强度的3个主要因素:水灰比、再生粗骨料取代率和再生细骨料取代率,并利用灰色数列GM(1,N)模型建立了再生混凝土砌块抗压强度的预测方程。结果表明:运用灰色关联系统理论分析再生混凝土砌块的抗压强度是可行的,且模型的预测精度能够满足要求。
The grey relational analysis method was used to study three main factors affecting com- pression strength of recycled concrete blocks, including water-cement ratio, recycled coarse aggregates re- placement ratio, recycled fine aggregates replacement ratio. The grey model of GM （ 1, N） predictive equa- tion was established to predict the compression strength of recycled concrete blocks. The results show that it is feasible to analyze compressive strength of recycled concrete blocks through the grey relational sys- tem theory, and the prediction accuracy of the model can meet the requirements.
