Review of selected aspects of shaping of physical, mechanical and thermal properties and manufacturing technology of lightweight and ultra-lightweight autoclaved aerated concrete

The paper provides an overview of selected scientific articles presenting research carried out in recent years on methods for producing autoclaved aerated concrete. Traditional technologies are briefly presented, together with innovative solutions for the production of low-density and ultra-low-density materials. In addition to the presentation of the manufacturing methods themselves, the results of research into the properties of the autoclaved aerated concrete obtained and their dependence on the technology used are also presented. A subjective selection and review of articles covering research into the thermal conductivity of concrete, the technological factors influencing them and the ways in which they can be shaped was also carried out. A significant number of the cited articles do not function in the world scientific circulation due to the language barrier (they are mainly in Ukrainian). In the meantime, they contain interesting research results which can inspire further research into the issues discussed concerning the production technology and the thermal and strength properties of autoclaved aerated concrete, with particular emphasis on lightweight and ultra-lightweight concrete.
