Fractal Study for Surface Cracks on the Recycled Concrete Beams with Recycled Bricks

Abstract:

In this paper, the experimental research on crack of four recycled aggregate concrete simple beams under a concentrated load was presented. Through the analysis of evolution and distribution characteristics of cracks with different amount of recycled brick, it is verified that the surface cracks on the recycled aggregate concrete beams have a very good fractal behavior. The research shows that the content of the recycled brick has obvious influence on the fractal dimension of the surface cracks of the beams. The more the content of the recycled brick is, the bigger the fractal dimension is. So the fractal dimension can be regarded as an index to evaluate damage degree of the recycled aggregate concrete beam. This research provides a novel idea and a method for studying the damage of the concrete structures.
