Self-heating potential of metashale mortar doped with carbon fiber dust

Popis výsledku v původním jazyce

Geopolymers are a very promising candidate to replace cementitious composites due to their significantly lower environmental impact and their potential for application in the field of multifunctional materials. New functional properties such as self-heating thus increase the possibility for geopolymers to be used in so-called smart structures. The ability to self-heat is directly affected by the electrical properties of the composite The key factor are the electrically conductive pathways within the material, which form an electrically conductive network through which electric current flows. Enhancement of the electrical properties can be achieved by applying electrically conductive additives such as carbon fibre dust (CFD). This paper is focused on the material characterization and verification of the self-heating ability of a multifunctional geopolymer mortar with CFD admixture. The sample was tested in AC mode to avoid polarization of the electrodes. With the AC power supply set at 30 V (RMS), the maximum temperature rise at the bottom of the sample from 23 to 32.1 °C was achieved in approximately 2 hours and the power meter recorded a power value of 2.6 W.
