Abstract. Results of researches of the developed wall material with the raised heattechnical characteristics on the basis of straw of cereal crops and a flax are presented in the article. The parameters of density, strength, and thermal conductivity of the samples depending on the ratio of astringent components are analyzed. The sorption humidity of the wall blocks at a relative humidity of 97% is determined. The kinetics of sorption of blastfurnace blocks is considered, and the thermal conductivity coefficient of the material at the maximum sorption humidity is established.
Key words: construction, cement, binder, fire, straw, cementlime stone, thermal conductivity, sorption humidity.
