- Abstract:
-
The surface of old concrete after rough treatment has fractal characteristics. Through the self-made roughness tester, the surface roughness of old concrete was evaluated by simple fractal method, and compared with conventional test methods. The data show that the fractal dimension and average sand filling depth have good linearity, which can be used as the roughness evaluation index of concrete. The measuring instrument is simple to operate and easy to use, which is suitable for measuring the surface roughness of old concrete in actual reinforcement projects.
