Abstract
The article deals with research on sustainable building materials - alkali-activated mortars with high temperature resistance. A cement-free alkali-activated binder [geopolymer] based on alkali-activated fly ash from coal combustion using perlite, perlite dust and cenospheres as filler. The object of the analysis was to study the effect of fillers on the coefficient of thermal conductivity, compressive strength and microstructure of the cementless mortars. The results showed that the most effective addition was perlite sand in the amount of 30%. The other tested lightweight fillers did not significantly change the thermal conductivity of the tested mortars.
