The article presents the results of a study of the thermal conductivity of non-autoclaved foam concrete based on microsilica, depending on its average density and humidity. It is established that the decrease of the average density of foam concrete from 800 to 400 kg/m 3 leads to a decrease the thermal conductivity coefficient by 44,9 %. The coefficients of thermal conductivity of the dry samples are about two times lower than the same samples at their natural humidity.
