Investigation of the Joule's effect in electrically enhanced alkali-activated aluminosilicates
Original language description
Alkali-activated aluminosilicates (AAA) are thanks to their high strength, enhanced fire resistance and good chemical resistance promising building materials. Furthermore, many AAA can be viewed as eco-friendly economically advantageous materials due to the fact that some industrial byproducts available for a reasonable price, such as blast-furnace slag or fly ash, can be used as their main components. Therefore, AAA can be considered as good competitors to widely used cement-based materials. AAA are in general electrically non-conductive. However, adding a sufficient amount of electrically conductive admixtures significantly decreases their electrical resistivity which broaden application possibilities. Enhanced materials can be used as self-heating or self-sensing systems. In the paper, AAA samples made of blast-furnace slag, water glass as an alkali activator, filler represented by three fractions of sand and electrically conductive admixtures were prepared. The ability to generate Joule heat is tested on samples loaded by an external DC electric source by means of measurements of temperature by K-type thermocouples in chosen points on samples. The obtained experimental data make it possible to identify a promising AAA which exhibits a sufficient increase of temperature in room conditions and can be utilized well in practical applications.
