Program
Our key topics
In autumn 2022 the Xella Technologie- und Forschungsgesellschaft mbH is organising a one-day scientific and technical colloquium devoted to the subject of Mineral building materials for climate-friendly construction.
The colloquium addresses the role of the Autoclaved Aerated Concrete (AAC) and Calcium Silicate Masonry Unit (CSU) industry in the transition towards a decarbonized built environment.
