Recently, RILEM TC 162-TDF Committee has proposed a specimen configuration, test procedures and flexural tensile
strength parameters to characterize the post-cracking behaviour of the steel fibre reinforced concrete (SFRC). The
approach proposed by RILEM is still yet under discussion, mainly, the ability of the flexural tensile strength parameters
to simulate the post-cracking behaviour of the SFRC on the verifications to the ultimate and serviceability limit states.
Taking the recommendations of the RILEM, the influence of the fibre content, the concrete age, and the percentage of
cement replaced by fly ash on the bending behaviour of the SFRC was analysed in the present work. The influence of
the fibre distribution on the fracture surface of the specimens was also considered. The experimental campaign was
carried out with a cost competitive SFRC developed for industrial pavements. Bending tests with concrete specimens
reinforced with conventional bars and steel fibres were also performed for developing a reinforcement system adjusted
for panels of industrial pavements heavily loaded. The results obtained are presented and analysed.Fundação para a Ciência e a Tecnologia (FCT) - POCTI/34793/99
