Depending on their specific use and the quantity used per cubic metre, most of the different types of fibres offer multiple properties, from anti-cracking up to replacing the iron reinforcements in part, and in some cases completely. A peculiar characteristic which defines fibres, is their aspect ratio, or the ratio between the diameter and the length of the fibre. The length/diameter ratio (L/D) must be between 35 and 65. The correct aspect ratio gives stability and homogeneous distribution to the cement matrix. Steel fibres are a valid solution in the preparation of floors in order to limit cracking. The recommended amount is approximately 30 Kg/m3. Higher proportions of fibre guarantee an increase in the breaking load, up to fully substituting the foundation mesh, if the slab is placed directly on the ground. Regardless, the use of fibres is subject to design specifications drawn up by a professional. Floorings made with steel fibre allow an increase in the size of the joining cuts up to 10 metres.
