Dielectric properties of porous cement mortar: fractal surface effects
(1991) In Solid State Communications 79(1). p.93-96- Abstract
- We have studied the electrical properties of cement mortars in the frequency range 10-4-107 Hz, for different water contents. The admittance scales as a power law with an exponent of about 0.7 in a wide frequency range. This behaviour is interpreted in terms of polarization and diffusion at fractal pore surfaces. We obtain a fractal dimension of 2.4, which is in good agreement with adsorption isotherm data for the mortar.
