Abstract :
Natural polycrystalline granite and marble were studied by broadband dielectric relaxation spectroscopy (10-2-106 Hz) at room temperature and several water contents (pure water) of the specimens. The results show a dramatic dependence of the complex dielectric permittivity on the water content of the specimens even for very low hydration levels
