Nguen Than′ Tuan, Oreshkin D. V.

The article presents the results of the selection and optimization of composition of gas-concrete mixture with additives that is produced in Vietnam. The authors carry out the studies to identify and compare the properties of autoclaved aerated concrete and non-autoclaved curing when adding metakaolin, silica fume and rice husk in the amount of 7 % into the mixture. It was found that gas concrete, which contains highly active metakaolin, shows the best properties.
