Abstract: A series of 40 precast prestressed roof elements has been cast, employing a self-compacting steel fibre reinforced concrete (SCSFRC). They are going to be used in a building of the Magnetti-Larco firm. The fibre distribution inside the roof elements has been investigated by means of a suitable test procedure and correlated with results obtained from cube samples drawn from the batches and tested at the fresh state. Companion slabs have been also cast and tested under four point bending, in order to investigate the existing correlation between fibre distribution and mechanical properties of the composite. The work here presented analyses the existing correlation between fibre distribution, workability and mechanical properties of steel fibre reinforced concrete (SFRC) with the aim to optimise both its fresh- and hardened-state properties in the sight of its use in a series production of precast SFRC structural elements.
