ABSTRACT: Fibre Reinforced Concrete (FRC) was a promising material a couple of decades ago but now is a reality. Fibres are now widely used for reinforcing industrial floors and for tunnel linings. In the beginning, steel fibres were used to enhance concrete toughness but, recently, different types of synthetic fibres were proposed in the market.

In the present paper, toughness of concrete reinforced with different types of steel and synthetic fibres was measured by means of bending tests on notched specimens. Furthermore, since fibres can be useful for limiting shrinkage cracking, early tests for comparing the efficiency of fibres in limiting the shrinkage cracks were performed. In addition, the benefits in terms of concrete toughness and shrinkage cracking of a

combination of polypropylene and steel fibres are presented. Finally, after determining the constitutive laws for cracked concrete, structural behaviour of slabs on grade and simply supported slabs was numerically simulated within the assumptions of Non Linear Fracture Mechanics.
