Optimization of electrode embedment for self-heating experiments of multifunctional geopolymers

Original language description

Self-heating construction materials belong to the group of multifunctional materials with high potential in the construction industry. Maximization of the self-heating potential of geopolymers / alkali-activated aluminosilicates / cementitious materials is mainly dependent on two factors. The first is optimization of the effective electrical conductivity of the material, which is crucially dependent on the amount of a chosen electrically conductive admixture. The second is the selection and way of fitting/embedment of a particular type of electrode on samples. Even a sufficient increase in the amount of electrically conductive admixture, which is directly proportional to the number of formed conductive paths within the solid matrix accompanied by an increase in the effective electrical conductivity corresponding to the amount of evolved Joule’s resistance heat, does not guarantee a good heating potential without an appropriate attachment of electrodes. In this paper, several types of electrode embedment were tested within self-heating experiments carried out on optimized multifunctional geopolymers with carbon black and graphite powder. Examples of errors observed during self-heating experiments due to failure of particular types of electrode embedment are presented. With respect to the observed failures, the electrode embedment was stepwise optimized
