摘要
碱激发煤矸石矿渣结合料是一种环保型材料,近年来在工程道路上被使用。通过正交试验,进行碱激发煤矸石矿渣结合料配合比设计优化。对正交试验结果的直观分析、极差分析、方差分析,得出配合比中各主要变量对碱激发煤矸石矿渣结合料的力学性能和孔隙率影响规律。实验表明,碱激发煤矸石矿渣结合料的抗压强度影响因素依据显著性的排序为:碱当量、骨料率、水胶比。碱当量对结合料的前期抗压强度影响程度大,骨料率对结合料的后期抗压强度影响大。
Alkali-activated coal gangue slag binder is an environmentally friendly material,which has been used in engineering roads in recent years.The mix ratio design of the alkali-activated coal gangue slag binder was optimized by an orthogonal test.Through the intuitive analysis,range analysis and variance analysis of the orthogonal test results,the influence of the main variables in the mix ratio on the mechanical properties and porosity of the alkali-activated coal gangue slag binder was obtained.Experiments show that the factors affecting the compressive strength of alkali-activated coal gangue slag binder are ranked according to significance:alkali equivalent,aggregate ratio,and water-binder ratio.Alkali equivalent has a great influence on the early compressive strength of the binder,and the aggregate ratio has a great influence on the later compressive strength of the binder.
