While recycled concrete building materials have already been used in roads and civil engineering projects, it is now being used in construction. The new research and laboratory building for life sciences on the North Campus of Berlin Humboldt University was built almost exclusively from a ready-mix concrete produced with aggregates from recycled concrete.

The team at Construction Demolition and Recycling takes a look at the benefits that can come from using aggregates from recycled concrete in construction as well as the process used to make the aggregates by Cemex Germany:

"This construction material is more complicated than standard concrete and it takes experience to handle it,” says Andreas Hanson, adding that "the production of such a concrete for building construction requires substantial expertise in concrete technology and chemical admixtures that, fortunately, is available at Cemex.”
