Vývoj tepelně-izolačního materiálu na bázi alkalicky aktivovaných systémů

Abstract

Alkali-activated systems are currently a widely studied group of alternative binders. However, its application in building industry is only rare. The dissertation deals with the development of alkali-activated systems based on finely ground blast furnace slag, with thermal insulating properties, where low density materials are used as fillers. In the experiment the use of liapor, expanded perlite, expanded vermiculite, ecostyrene, siopor, foam glass, waste aerated concrete, recycled cork, waste wooden chips and waste of technical hemp was tested. The experimental work was focused on the determination of the basic physical-mechanical properties and the thermal conductivity coefficient of the prepared materials. The values of the compressive strengths and thermal conductivity coefficients of the tested composites qualitatively correspond to the commercially available building materials.
