Overview of the materials used in the CUBE

The article provides a general description of the building mate-rials used for the two building parts BOX and TWIST of the car -bon reinforced concrete building CUBE. The focus of the article is on the presentation and explanation of the decisive material properties of those building materials that are not yet subject to a product standard and whose use was therefore subject to approval in individual cases (in German: Zustimmung im Einzel-fall, ZiE). These included seven different concretes, three car -bon fabrics, two different carbon rods, glass fibre rods and three high-performance insulating materials.
