The durability of autoclaved aerated concrete / Dauerhaftigkeit von Porenbeton

In order to be able to better assess the durability of autoclaved aerated concrete, a number of research activities have been carried out in the past. As a result of these studies, a new requirement was defined for autoclaved aerated concrete. The overall shrinkage rate, tested according to DIN EN 680, must be smaller than 0.4 mm/m. This article describes and discusses contributing factors and the background to this new requirement.
