## 2 Materials and Methods  
### Materials  
In this work, the following raw materials were used for the manufacture of non-autoclaved aerated concrete: Portland cement grade CEM I 42.5 N produced by JSC Novorossicment (Novorossiysk, Russia); river sand, alluvial sand from the Aksai quarry (Aksai, Russia); ground blast-furnace slag (GBFS) produced by NLMK JSC (Lipetsk, Russia); MK-85 microsilica (MS) produced by NPP ZIP (Lipetsk, Russia); PAP-1 aluminum powder produced by SKIF LLC (St. Petersburg, Russia); molding gypsum G-6 B III produced by Magma LLC (Moscow, Russia); and lump quicklime produced by Roskhimprom LLC (Rostov-on-Don, Russia). Characteristics of raw materials are shown in Tables 2-7.

\begin{tabular}{c} As a replacement for \\ fine aggregate \\ \end{tabular} &
\begin{tabular}{c} The addition of granite dust particles increases the \\ compressive strength and density of the hardened aerated \\ concrete and reduces water absorption and porosity. The \\ maximum increase in compressive strength was observed \\ at the level of 42\% for a mixture containing 20\% \\ replacement of fine aggregates with granite dust. \\ \end{tabular} \\ \hline

\begin{tabular}{c} As a binder \\ replacement \\ \end{tabular} &
\begin{tabular}{c} The results of the study show that the use of expanded \\ perlite waste in aerated concrete leads to a decrease in its \\ density, and the thermal conductivity and compressive \\ strength of the samples decrease as the percentage of \\ expanded perlite in aerated concrete increases. \\ \end{tabular} \\ \hline \hline \end{tabular}
