Abstract
The present article compares grades of cellular concrete in terms of sorption moisture as a significant performance characteristics of building materials for enclosing structures. The studies conducted in accordance with GOST 12852.6 used D400, D600, and D800 non-autoclaved cellular microsilica concrete, as well as D500 and D600 autoclaved aerated concrete. During the study, sorption isotherms of cellular concrete were plotted for the relative air humidity range of 57–100%. According to the conducted experiments, the relative air humidity growing from 57 to 100% increases the sorption moisture of non-autoclaved cellular concrete with an average density of 400, 600, and 800 kg/m3 by 3.67, 5.58, and 5.37 times, respectively. For autoclaved aerated concrete samples with an average density of 500 kg/m3 and 600 kg/m3, the increase is 10.85 and 10.69 times, respectively. The obtained results have proved the value of sorption moisture depending less on the average density of cellular concrete as compared to the density and water resistance of interpore partitions, which are most affected by the hardening conditions of cellular concrete.
