| Abstract: | The development of the cracks on concrete surface influences the erosion of the reinforcing steel bar.The present research performs erosion experiment of the reinforced concrete with force cracks,the load crack devolping rule on the concrete surface and the corresponding effect on the infection of the reinforcing steel bar erode is studied by means of fractal theory.This paper investigates the feasibility of fractal theory application on the estimate of reinforced concrete damnification and durability. |
