Original Abstract
The paper deals with the comparison of the thermal and dielectric properties of alkali-activated aluminosilicates containing the conductive admixture in the form of carbon fibers. To determine the thermal conductivity and thermal capacity of the system, a differential method based on the response to the step wise heating was used. The electrical conductivity and the capacities were determined by impedance spectroscopy. For both electrical and thermal properties, a model was created which allowed the determination of the characteristics of individual processes. The analysis of these models showed that the thermal conductivity of material decreases with increasing concentration of admixtures, probably because of greater porosity of material. For the concentration of 2.22% it is about three times smaller than for the concentration of 0.11%. The heat capacity is reduced at concentrations higher than 1.11%. The electrical conductivity decreases with increasing concentration of the admixture, which again seems to be related to greater porosity of material. For the concentration of 2.22% it is more than four times smaller than for the concentration of 0.11%.
