Steel Fibre Reinforcement

These little staple-like items are steel fibre reinforcements. They are added to concrete in order to increase strength, making it possible to create complex shapes and structures out of concrete that would previously have collapsed. Prior to being mixed into the concrete, they are glued together in bundles; this way they are mixed together easily and uniformly throughout the concrete. There are a variety of sizes available, and can be used to create varying degrees of strength in concrete and enable new architectural possibilities. Such reinforcements can be seen in tunnelling projects and in structures including the CCTV building in China and the Oceanographic in Valencia, Spain.
