For the "Stuttgart 21" traffic construction project, chalice-shaped pillars are being built for the roof of the main railway station. In order to ensure compliance with the concrete covering, spacers made of fibre concrete are used on the reinforcement of the columns.
Sorp 10® sound absorbers integrated into the concrete ceiling ensure good room acoustics and reduce reverberation time. In combination with Sorp acoustic plaster, a jointless, homogeneous ceiling design is achieved.
The use of ecologically safe and recyclable building materials was a clear objective of this project. Geothermal heating in combination with Sorp 10® reduces the energy requirement enormously and ensures pleasant room acoustics in the open areas.
The requirements for shuttered fair-faced concrete surfaces are particularly high for representative structural elements in building construction. For this purpose, spacers with a minimum contact area are recommended in order to avoid marking the contact points.
