Electrical properties and self-heating ability of alkali-activated slag with graphite powder
Popis výsledku v původním jazyce
Alkali-activated aluminosilicates and geopolymers in the dry-state are typical dielectrics which is a limiting factor for their utilization in new sophisticated ways in construction industry. Nevertheless, such an issue can be solved by using various electrically conductive admixtures to attain reasonable electrical properties that ensure new functional properties, such as self-heating or self-sensing. Self-heating ability is attained by the addition of electrically conductive aggregates or sufficient amount of metallic or carbon-based powders or fibers ensuring a significant increase in electrical conductivity. However, the self-heating was studied mainly for cementitious materials. Taking into consideration good materials properties of alkali-activated aluminosilicates and geopolymers, such as good mechanical properties, chemical resistance, and durability together with the lack of research concerning electrically enhanced multifunctional materials, it is obvious the necessity of new studies. In this paper, alkali-activated ground-granulated blast-furnace slag composite with graphite admixture was studied in terms of basic physical and electrical properties together with the experimental verification of self-heating ability. It was proved that the designed composite with 35 wt. % of graphite powder can be classified as multifunctional material that could be utilized in special applications, such as snow-melting pavements, snow-melting roads or self-heating construction elements.
