混凝土细骨料级配的分形特征研究

Research on Fractal Characteristics of the Size-Distribution of Concrete Aggregates

利用分形几何学原理对混凝土骨料级配进行研究 ,发现混凝土组成材料具有许多明显的分形现象 ,因此认为分形可以成为对混凝土研究的一种有效的新的方法。建立了骨料级配与分维值D的关系 ,以及分形体积V、分形孔隙率P与分维值D的关系。

The size distribution of concrete aggregates is analyzed by using the principle of fractal geometry theory. The results indicate that the composition materials of concrete have many obvious fractal phenomena, and hence the fractal theory can become a new effective approach to researches on concrete. The relationships of fractal dimension D versus the size distribution of aggregates, the volume fractal dimension V , and the porosity fractal dimension P are established.
