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 me...

Cement-based composites belong to the most frequently used construction materials in the world which is mainly for their good mechanical properties and durability. However, production of cement exhibits significant impact on environment due to a high amount of consumed energy and CO2 emissions. Therefore, alternative environmental-friendly construction materials with comparable materials properties are currently intensively studied. Geopolymers based on alkali activation of waste precursors exhibit lower impact on...
