Influences of aggregate on microwave absorbing properties of porous Concrete

摘要

The key factors for reflection loss of porous materials were studied mainly through experimentation. Regarded aggregate particles as polydisperse particles in porous concrete, by introducing Mie solution on scattering by a spherical particle, and combining with independent scattering discipline for polydisperse particles, a theoretical method for calculating microwave absorbing properties of porous concrete with aggregate diameter in logarithm normal distribution is presented, which can forecast the absorption properties of porous concrete preferably.
