ABSTRACT
Electrical data can be presented in a variety of formalisms, (i) the use of complex-plane plotting techniques
as an aid in developing an equivalent electrical model for the impedance response and then ascribing a physical interpretation to the model. This format of presentation is extensively used in the study of ceramics and solid state ionic materials and has been transferred to cement-based systems;
(ii) to present the electrical response in terms of the intrinsic electrical properties of the material in the frequency domain. This format of presentation is undertaken to identify the fundamental processes which give rise to electrical response.
