| 摘 要： | 混凝土存在着分形现象,骨料粒径、级配等分形计算方法已有研究,而对于用砂石分形指标计算骨料的密实度研究较少.对混凝土骨料进行试验研究,进一步分析骨料分形规律,提出基于分形的骨料密实度计算公式.试验表明:该公式能够较好的预测骨料按不同质量比混合时的密实度,从而为混凝土配合比设计提供参考. |
| 关 键 词： | 骨料分形 骨料体积分形 骨料密实度 |

| Abstract: | Fractal phenomenon exists in concrete.Fractal calculation formulas of aggregate size,gradation et al.Were proposed by scholars.However,the study about the calculation method of aggregate packing degree using aggregate fractal indexes is not available.The aggregate packing degree calculation formulas using fractal theory based on experimental studies and further analysis on concrete aggregate fractal laws were proposed.Test results indicate that the formula can calculate aggregate packing degree according to... |
