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...

The massive depletion of natural resources, together with the inefficient use of end-of-life materials, results in the generation of vast amounts of waste. The waste material recycling poses a challenge for the present generation and alteration of current material streams needs to be reconsidered to mitigate the consequent environmental burdens. The construction industry produces several millions of tons of brick debris which remain landfilled or, at the best, are used as a substitute for natural aggregates. Howev...
