Abstract
This paper presents basic electric properties of laboratory prepared alkali-activated
composite materials on the basis of finely ground granular high furnace slag to which various
quantities of carbon nanotubes (CNT) have been added. Impedance spectroscopy in the
frequency range from 40 Hz to 1 MHz was used to measure the specimens. Electric resistivity
versus frequency and electric resistivity versus CNT content relationships were examined
on our specimens R&S ZNC vector analyser with DAK-12 coaxial probe (made by Speag)
was used to carry out the measurements at higher frequencies (from 100 MHz to 3 GHz).
Electric conductivity as a function of the frequency and as a function of the specimen CNT
content was studied in this frequency range. Up-to-date instruments and a unique approach
have evidently been employed to carry out non-destructive measurement of mortar materials.
