The use of dielectric models to determine moisture content in aggregate material

Abstract

This paper provides a preliminary study on the properties of dielectric modeling when applied to composite aggregate materials under the action of Time Domain Reflectometry (TDR). While only the bounds of the values are determined, results indicate that models that take account of ionic exchange processes can come close to representing composite aggregate material. For high precision work however these existing models are not be accurate enough and a new mixing model is required.
