摘要/Abstract

摘要： 为解决多因素共同作用下单个控制因素对碱激发矿渣-粉煤灰胶凝材料力学性能的影响显著性问题,本文研究了粉煤灰掺量、水胶比、碱掺量和碳酸钠掺量对碱激发矿渣-粉煤灰胶凝材料抗压强度的影响,并利用灰色关联分析和基于正交试验设计的单变量方差分析、极差分析评价上述因素对力学性能的影响程度。结果表明:在NaOH/Na₂SiO₃激发矿渣-粉煤灰胶凝材料体系中,粉煤灰掺量对抗压强度起主要影响作用;此外,建立了粉煤灰掺量、水胶比、碱掺量、碳酸钠掺量与抗压强度之间的预测公式,预测结果与试验结果相对误差基本控制在±10%以内。

Abstract: To address the significant impact of a single control factor on the mechanical properties of alkali-activated slag-fly ash binder materials under the combined action of multiple factors, the effects of fly ash content, water cement ratio, alkali content and sodium carbonate content on the compressive strength of alkali-activated slag-fly ash binder materials were investigated. Grey relational factors and univariate analysis of variance and range analysis based on orthogonal experimental design were used to evaluate the degree of influence of these factors on mechanical properties. The results show that in NaOH/Na₂SiO₃ alkali-activated slag-fly ash binder material system, fly ash content has a major impact on compressive strength. A prediction formula has been established to accurately predict the relationship between fly ash content, water cement ratio, alkali content, sodium carbonate content, compressive strength. The relative error between the predicted results and experimental results is basically controlled within ±10%.
