%X The cement is an essential material for the development of the civil construction. The analysis of cement-based materials is useful to evaluate mechanical properties, water absorption, air permeability or evolution of hydration degree. This last one is the motivation of this paper. New advantageous techniques of analysis based on the image information are possible through of electronic microscopy. We propose here an alternative procedure to the segmentation of microstructures of cement and aggregates in concrete. The central idea consists of a particular use of the morphological operator watershed. We report the result of the analysis of about 450 Scanning Electron Microscope (SEM) images.
