Localization of concrete fatigue defects in concrete CT images based on fractal theory

摘要

Defects information of aperture and crack etc. in concrete is very important for life of concrete. In this paper, X-ray CT is used to scan microstructure of concrete to get CT image of cracking, extension and connexity in inner CT scale of concrete specimens. Based on Fractal Theory, defect distribution in concrete inner may be identified by manipulating image.
