The electric permittivity is a material property that relates to the dielectric and electromagnetic behaviors. This work reports the effect of polymer admixtures on the permittivity (2 kHz) of cement paste. The permittivity is increased significantly by the addition of either methylcellulose (dissolved) or latex (styrene–butadiene, not dissolved), due to the capacitance of the interface between polymer and cement. The permittivity is effectively modeled by a material-level equivalent circuit…
