self-compactibility requirements. A crushed granite coarse aggregate (CA) with a maximum aggregate size of 12 mm, a fine sand (FS) and coarse sand (CS) were adopted. A content (Cf) of 60 kg/m3 of hooked steel fibres with a length, If, of 33 mm, a diameter of 0.55 mm, df; and a yield stress of 1100 MPa was used. The fresh state behaviour of concrete was determined by the Abrams cone slump test in the inverted position according to [18], having been obtained a spread diameter of approximately 590 mm.

The compressive strength was assessed by testing 6 cylinders with a diameter of 150 mm and a height of 300 mm at the age of 28 days. After casting, the specimens were stored in a climatic chamber room at constant temperature of 20 °C and relative humidity of 60 %. An average compressive strength and an average young modulus of 72 MPa and 42 GPa was obtained, respectively, with a coefficient of variation (CoV) of 8.2 and 0.3 %, respectively.
