Characterisation of diffusion paths of water in concrete by color image analysis

Abstract
The scope of this paper is to investigate the dispersion of air-voids in concrete. Different automatic methods of image analysis are proposed to characterise this dispersion and the distribution of path lengths fiom given points of the cement paste to the air-voids, using euclidean or geodesic processes. It is shown that the distances between air-voids increase with gravel content and that geodesic distances are higher than the euclidean ones.
