Three recycled concrete beams with the different gradation of coarse aggregates under concentrated load are presented. By using fractal theory, the distribution of the surface crack growth of the recycled concrete beams is analyzed. The results indicate that the surface crack of three recycled concrete beams show self-similarity of fractal behavior. The relationships between the fractal dimension and the damage variable and loads are established separately. The fractal dimension reflects the destructive degree of the recycled concrete beams.
