Original Abstract

Autoclaved aerated concrete is one of the few building materials whose production can use up to 70% of energy by-products. These by-products include fly ash from high-temperature as well as fluidized coal combustion and energogypsum. In addition to the raw material composition, one of the prerequisites for the production of aerated concrete with good physical and mechanical properties is the right choice of autoclaving mode. This mainly refers to the length of the isothermal heating phase and, obviously, to the appropriate choice of temperature and the related pressure in the autoclave. This article reviews the microstructure and physical-mechanical properties of aerated concrete autoclaved in three different modes. Particular attention is paid to tobermorite as the majority mineral of aerated concrete, especially to the shape and quality of its crystals.
