Abstract
Researches on studying of heat-insulating properties of the obtained geopolymeric foamed concretes on basis of brick wastes were conducted. Content of alkali solution in the initial composite was varied at the level of 20%mass. The composite with ratio of brick wastes to binder equal 80:20 was taken for research. Volume weight of the researched specimens was varied from 558 kg/m3 up to 1656 kg/m3 . Temperature of heat flow meter was kept up at the level of 40, 50 and 600C. It was established that specimens with volume weight 558 kg/m3 at temperature 600C have the least value of coefficient of thermal conductivity which makes up 0.03 W/(mK). It was also established that the obtained specimens of geopolymeric foamed concrete can be recommended for the using as heat-insulating materials. Keywords: geopolymer, foamed concrete, coefficient of thermal conductivity, brick wastes.
