Drying of building materials and soils plays a major role in their final properties and is a main economics and environmental issue. In this thesis, we study the drying of complex porous media to better understand the impact of particles in the interstitial fluid. With a clear scale separation between the sample, pores and particles sizes, we observe water and particles distributions by camera, MRI, X-ray tomography and confocal microscope. We show that the fluid evolution and the drying kinetics are coupled. We study three kinds of fluids: pure liquid, hard and soft particles suspensions. The drying rate of pure water remains constant and generally persists until the majority of water is evaporated. The fluid flows through the porous netwo...
