Basic physical, mechanical and electrical properties of electrically enhanced alkali-activated aluminosilicates

Popis výsledku v původním jazyce

Alkali-activated aluminosilicates (AAAs) with electrically conductive admixtures are promising competitors to the cement-based materials enhanced in the same way. The electrical conductivity of these materials dramatically increases with a sufficient amount of admixtures, which broaden their possible applicability. Electrically optimized materials are typically used in self-heating, self-sensing or magnetic-shielding systems. However, an increase in the amount of admixtures can negatively affect the compressive or flexural strength and can lead to an increase in the porosity. Therefore, it is crucial to experimentally determine the mechanical properties in order to decide whether an electrically enhanced material is applicable in the building industry. In this research, basic physical, mechanical and electrical properties of AAAs with three types of electrically conductive admixtures in different dosages are studied. Typical representatives of spherical inclusions, carbon black (CB), graphite powder (GP) and carbon fibers (CF) as fibrous fillers, are tested. The experimental results reveal that AAAs with CB dosages higher than 4 % are promising materials that could be utilized in self-heating systems due to their sufficiently high electrical conductivity.
