These materials knew a big success which results from their capacity to be conceived "à la carte". Indeed, one can modify their behaviour by acting on the nature and properties of the constituent materials, the geometry of inclusions (shape and dimensions), their concentration, orientation and position within the host material (matrix). However, some problems that can affect their performances can occur during their exploitation leading to the appearance of cracks, cavities, water within these cavities and to the deterioration of reinforcements resulting of various stresses (chemical attack, heating, earthquake, non adequate proportioning …). Thus it’s important to characterise these composite materials at their conception and to follow the evolution of their properties during their exploitation. This work is aimed at the characterisation of building materials consisting of three dimensions homogeneous matrices (host matrix) and dielectric/conducting inclusions using a non destructive method. This method combines two methods: dielectric and electric. These both methods enable to evaluate the presence of inclusions, their concentration and their nature in a given heterostructure. The samples we considered are of cubic shape; they consist of cement paste containing air cavities, cavities filled with water, steel and glass inclusions. The obtained results are very encouraging and makes the method we developed an interesting tool for building engineering applications.
