Environmentally friendly material solutions in the technology of autoclaved aerated concrete

Autoclaved aerated concrete is an environmentally friendly material. However, the demands of the modern world and, above all, care for the future, necessitate the search for new solutions to minimise negative environmental effects. This paper presents selected solutions for the use of waste materials and by-products from other techniques in autoclaved aerated concrete production, taking into account potential risks and limitations. Attention was also drawn to the use of aerated concrete waste in other methods, primarily as a cement substitute, or concrete additive. The paper is selective in nature due to its volume, but the main purpose is to present trends and directions in the search for new material solutions in this technology.
