Electrical Properties of Environmental-friendly Self-heating Composite Materials
Original language description
Cement-based composites belong to the most frequently used construction materials in the world for their good mechanical properties and durability. However, production of cement exhibit significant impact on environment due to high amount of consumed energy and CO2 emissions. Therefore, alternative environmental-friendly construction materials with comparable materials properties are currently intensively studied. Geopolymers are materials based on alkali activation of various precursors that exhibit lower impact on environment. Innovative approach lies in design of multifunctional construction materials that can together with good mechanical properties and durability e.g. evolve heat, detect the current material condition or harvest energy from various ambient energy sources. Such desired capabilities can be ensured by geopolymers doped by electrically conductive admixtures in an appropriate amount. In this paper, self-heating geopolymer mix based on ground granulated blast furnace slag and carbon black is designed and characterized in terms of basic physical, mechanical, thermal and electrical properties. Electrical properties that are crucial for self-heating ability involve experimental determination of the electrical conductivity and volt-ampere characteristics. Finally, the self-heating experiment is conducted by acting of an external power source. The obtained results showed that self-heating ability of the designed geopolymers is promising and such materials can be classified as multifunctional. Taking into account materials properties comparable with cement-based materials and the fact that ground granulated blast furnace slag is a waste product, the designed geopolymer can be considered as environment friendly compared to the materials based on Portland cement.
