The purpose of this study is to analyse the effects of fibre volume fraction on the mechanical properties of SFRC (Steel Fibre Reinforced Concrete). The results obtained from compression and four-point bending tests carried out on concrete specimens with fibre volume fraction of 1%, 1.6%, 3% and 5% are critically examined. The experimental behaviour in terms of peak load, post-peak behaviour, and residual strength, are evaluated and compared. The fibre distribution and their contribution in Mode I fracture is also assessed. The effects of steel fibre volume fraction on the strength, ultimate strain and ductility index of SFRC are highlighted in order to give a guide for structural use. © 2014 Lidia Rizzuti and Francesco Bencardino.

Abstract
The purpose of this study is to analyse the effects of fibre volume fraction on the mechanical properties of SFRC (Steel Fibre Reinforced Concrete). The results obtained from compression and four-point bending tests carried out on concrete specimens with fibre volume fraction of 1%, 1.6%, 3% and 5% are critically examined. The experimental behaviour in terms of peak load, post-peak behaviour, and residual strength, are evaluated and compared. The fibre distribution and their contribution in Mode I fracture is also assessed. The effects of steel fibre volume fraction on the strength, ultimate strain and ductility index of SFRC are highlighted in order to give a guide for structural use. © 2014 Lidia Rizzuti and Francesco Bencardino.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
