“…For a crack width less than 100 lm, steel fibers do not seem to affect the permeability [37]. The permeability of SFRC decreases significantly by increasing the fiber content and the curing time period [46].

h i g h l i g h t sMechanical properties and durability indicators of SFRSCC and SCC were assessed. Self-compacting requisites were maintained, adding 60 kg/m 3 of steel fibers to SCC. Steel fibers contributed for the increase of post-cracking flexural resistance. The addition of steel fibers to SCC did not affect the durability indicators. a b s t r a c tDurability is one of the most important aspects of concrete due to its fundamental incidence on the serviceability working conditions of concrete structures. Research on the durability of steel fiber reinforced self-compacting concrete (SFRSCC) is still scarce, particularly in the aspects of corrosion resistance, which did not yet demonstrate clearly whether the corrosion of steel fibers may or may not lead to cracking and subsequent spalling of the surrounding concrete.For conventional concrete, without steel fibers, there are some widespread used durability indicators, which applicability to SFRSCC and its common values are practically unknown. For this purpose, an experimental work with SFRSCC and self-compacting concrete (SCC) specimens was carried out in order to characterize their mechanical properties and evaluate durability indicators.The results showed that the addition of steel fibers to SCC was very effective in terms of increasing the post-cracking flexural resistance and the energy absorption, and did not affect significantly the selfcompacting requisites and the durability indicators of SCC.

“…The role of fibers in cement mortar [8] is not only to overcome the traditional weakness of inorganic cements, namely poor tensile strength and brittleness [4] but also to improve the resistance to impact, blast, explosion and other forms of dynamic loads when large amounts of energy are suddenly imparted to the structure [9]- [14]. The research carried out in the last few decades has established that the addition of short and discrete fibers to plain concrete or cement mortar enhances its engineering properties like compressive, tensile and flexural strengths and also its toughness [15]. When fibers are added to cementitious composites, they also control the propagation of cracks and limit the crack widths [16]; fibers bridging a crack can absorb energy by deforming and/or pulling out, depending on their bond characteristics; and the total energy absorption capacity of a material is enhanced by the mechanism of increase in the path of the cracks during separation or improvement in the material's capability to deform [17].…”

“…Roziere et al (2009) advocated it and stated that fibers block the capillary channels in the mortar and makes capillary pores smaller [31]. Moreover, fibers reduce diffusion channels of CO 2 by reducing micro cracks in concrete.…”
