We know that concrete has many strengths. We do also know that concrete has a weakness. Its resistance to aggressive media, in particular, biogenic sulfuric acid is just this weakness that is difficult to defy. But as concrete plays an essential role in infrastructure and our sewer system, the topic of sustainability cannot be met with excuses, but only with solutions. Sustainability is a principle that is actively followed at the Betonwerk Bieren precast plant and that is paid particular attention in any product development and process improvement. As a result, self-compacting concrete was already introduced in the production around 10 years ago, being implemented with the aid of elaborate production control. We were able to realize high process reliability at a consistent quality thanks to a stable concrete composition.
