The introduction of steel fibres into a concrete matrix to improve its mechanical characteristics is quite known and established in FRC technologies.

Abstract
their related negative impact on the environment. One of the strategies to reduce this impact is represented by the recovery of the constituent materials to be reused as raw materials in different technologies, including concrete products. The introduction of steel fibres into a concrete matrix to improve its mechanical characteristics is quite known and established in FRC technologies. Generally, steel fibres are used as discontinuous reinforcement of the concrete matrix to limit the cracking growth and to enhance the post-cracking behaviour. Thus, the obtained concrete is characterized by an improvement of its toughness and its post-cracking residual strength. The results of an experimental campaign, carried out at the University of Salento, will be discussed herein. This work is a part of a wider research project aiming to introduce recycled materials as new raw constituents in concrete mixtures such as in the production of precast panels. The results of experimental work underline the good reproduction of the laboratory scale in production plant.
