摘　　要：通过对比密实粉末状及颗粒状集料的表面能参数,明确表观特性对集料表面能参数会造成差异性影响.采用灰色关联分析法,分析三项表观特性指标对集料表面能参数的影响程度.结果表明:棱角性、表面纹理以及球度这三项表观特性指标对集料表面能的影响程度依次降低.基于集料表观特性指标和粉末状集料表面能提出了颗粒状集料表面能参数的预测模型.By comparing the surface energy parameters of dense powder and granular aggregate,it is clear that apparent characteristics will have different effects on the surface energy parameters of aggregate.The influence of three apparent characteristics on the surface energy parameters of aggregate was analyzed by grey correlation analysis.The results show that the influence of three apparent characteristics,such as angularity,surface texture and sphericity,on the surface energy of aggregate decreases in turn.Based on the apparent characteristics of aggregate and the surface energy of powdery aggregate,a prediction model of surface energy parameters of granular aggregate was proposed.
