Self-heating Experiment: Alkali-activated Aluminosilicate with Carbon-based Admixture

Popis výsledku v původním jazyce

In the present, traditional building materials with an adjusted composition are widely studied in terms of sophisticated applications. Self-heating ability of cement-based materials and geopolymers is based on supplementing the originally non-conductive material by electrically conductive admixtures. Addition of electrically conductive metal-based or carbon-based admixtures results in a significant increase in the electrical conductivity of such composites which is a crucial assumption for generation of heat by the action of an external electric source. Such materials can be then practically used in self-heating constructions, such as in pavements, bridges or self-heating elements used in interiors and exteriors of the buildings. Within the research, alkali-activated aluminosilicate with 11.1 wt% of carbon black (CB) admixture was designed, material parameters necessary for the successive calculations were experimentally determined, self-heating experiment was carried out and FEM calculations were conducted in order to validate the proposed heat model. It was observed good agreement of the modeled data with the experimentally determined data.
