Fiber-reinforced concrete consists mainly of steel, glass or plastic fibers. Steel fibers are the most suitable because they have high tensile strength and a high modulus of elasticity. In addition, they are non-flammable and provide corrosion resistance in the dense, alkaline concrete. By admixing steel fibers, which have a crack-bridging effect, the cracking and fracture behavior, ductility, energy absorption and impact resistance are significantly improved. However, it is not possible to precisely intersperse the fibers.
DUCON®, on the other hand, relies on spatially linked micro-reinforcement consisting of steel mats layered on top of each other without individual fibers. The reinforcement package can be precisely adjusted and can be used for any cross-sectional shape. In addition, the scatter in material behavior is minimal.
