Abstract:
The interfacial zone separating cement paste and
aggregate in ortar and concrete is believed to influence
many of the properties of these composites. This paper
presents a theoretical framework for quantitatively
understanding the influence of the interfacial zone on
the overall electrical conductivity of mortar, based on
realistic random aggregate geometries. These same ideas
may also be used to approximately predict the fluid
permeability of mortar.
