Recent research is evidencing that adding steel fibres recycled from wasted tires can
improve the post-cracking behaviour of cement based materials, enhancing the ductility, energy
dissipation and impact resistance of elements made by this type of composites. As a consequence,
Recycled Steel Fibre Reinforced Concrete (RSFRC) appears as a promising candidate for both structural
and non-structural applications. To contribute for the assessment of the potentialities of RSFRC, an
experimental program composed of three series of notched beam bending tests with concrete reinforced
with 45, 60 and 90 kg/m3 of recycled steel fibres (RSF) was carried out by determining the post-cracking
residual strength parameters, fR,,j, defined according to the recommendations of the CEB-FIP Model Code
2010. Based on the obtained fR,,j, the constitutive laws characterizing these three RSFRC were determined
and used to estimate the reinforcement potentialities of RSFRC for structural applications. A data base
with fR,,j corresponding to industrial steel fibres (ISF) was built in order to compare the post-cracking
performance of RSFRC and concrete reinforced with Industrial steel fibres (ISF). This paper describes the
experimental program, and presents and discusses the obtained results
