Analysis of concrete structures is usually carried out by destructive methods. The internal volume flaws directly influence concrete properties. Such inclusions are empty or even resulting from the manufacturing process or degradation by percolation leaching dissolution and chemical reactions between its constituents. Industrial tomography systems (ITS), have proved to be a powerful tool for analysing and determining internal objects. In this context, this work aims at showing that it is possible to generate representative triangular meshes from real samples of concrete from data obtained with 3D ITS and use them to simulate mechanical properties in COMSOL Multiphysics® software. The results of these simulations can be used to compare them with the results of mechanical strength obtained in laboratory.
