Fibre concrete is the term used to describe concrete building materials that are reinforced with fibres made of steel, glass or plastic. Under certain conditions, conventional reinforcement by means of meshes and bars can be completely dispensed with. Fibre-reinforced concrete offers the advantage that the concrete layer can be installed in a single operation, without prior reinforcement.
In the case of fibre concrete, steel fibres are added to the concrete, and in some cases fibres made of glass or plastic. The fibres take over the tensile function within the material and have a positive influence on its load-bearing behaviour. The type, shape, direction and, above all, the quantity of the fibres determine the degree of static effectiveness. Under certain circumstances, this means that the reinforcement of a component made of steel meshes and bars can be completely omitted, and thus the entire reinforcement process. Fibre reinforcement can also be optimally used in precast or semi-precast walls in precast plants. Fibre concrete has only recently been included in the concrete standards, so that the usual building authority approvals will no longer be absolutely necessary in the future.
