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

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.
