High Strength Concrete
In order to boost resistance against percussive or striking attack, the toughness and flexural strength of the concrete must be improved. This can be achieved with the use of fiber reinforcements in the mix. With the addition of fibers made of various materials and different shapes, the ductility and tensile behavior of concrete can be increased. High strength and above all ultra high strength concrete are practically always also fiberreinforced. Depending on the requirements, synthetic and/or steel fibers are thereby employed in large quantity. The high flexural strength of UHPC can be achieved in this way.
