This study examines cellular aerated concretes based on polymer compositions and their standardization as lightweight
construction materials for the construction industry of Uzbekistan. The results of large-scale research and analysis indicate that adding
a 3% aqueous solution of CMC (carboxymethyl cellulose) to the composition of cellular aerated concrete improves product quality and
increases the strength grade of lightweight non-autoclaved cellular concrete. The efficiency of non-autoclaved aerated concrete was
enhanced by controlling the formation of the polymer structure in a dispersed system with a composite binder. As a result, the optimal
ratio of CMC to composite binding materials for the production of lightweight cellular concrete was determined. The role of a 3%
aqueous CMC solution in forming the porous structure of non-autoclaved aerated concrete based on composite binders was substantiated.
In addition, the moisture resistance, frost resistance, and thermal conductivity stability of cellular aerated concrete with optimized highly
porous composite structures were evaluated. The role of ingredients in the composite binder containing different proportions of CMC
was identified, and principles for producing aerated concrete with improved properties were developed. A methodology for producing
lightweight cellular aerated concrete compositions containing a 3% aqueous CMC solution was proposed, and the optimal proportions
of primary and auxiliary raw materials were determined. A technological guideline for producing lightweight non-autoclaved cellular
aerated concrete based on a 3% aqueous CMC solution was also developed
