      <dc:description>The electrical properties of carbon nanotubes (CNT) cement-based composites have been modeled in previous&#xd;
works by circuit models or homogenization theories. An alternative approach is the use of an effective medium&#xd;
theory with induced polarization: In this work, a new model based on the generalized effective medium theory&#xd;
of induced polarization (GEMTIP) with cylindrical inclusions is proposed. The presented results and discussion&#xd;
show its applicability to interpret the electrical impedance spectra of cylindrical cement samples doped with&#xd;
multi-walled CNTs (MWCNTs). The MWCNTs were dispersed in different media: one nonionic surfactant, two&#xd;
superplasticizers, a cationic type polycarboxylate ether, and an anionic type naphthalene sulfonate. Particle&#xd;
dispersion and their sizes were analyzed by Ultraviolet–Visible (UV–Vis) spectroscopy, and Scanning Electron&#xd;
Microscopy (SEM) measurements. Two electrode electrical impedance spectra were measured and analyzed by&#xd;
circuital models and the proposed GEMTIP model. The results demonstrate the efficiency of the proposed model&#xd;
in describing the Alternating Current (AC) response of cement/CNT composites irrespective of the dispersant&#xd;
agent used to elaborate the samples.</dc:description>
