“…The study by Tsukamoto and Worner [24] indicated that the fibres in the concrete reduces the flow rate at a given crack width and increases the critical crack width below which no further flow occurs. Improved resistance against permeability of cracked steel fibre reinforced concrete and mortar over cracked ordinary concrete/mortar is also reported by Lawler et al [25] and Rapoport et al [26].…”

Abstract:This paper reviews and presents various durability properties of strain hardening fibre reinforced cementitious composites (SHFRCC). Published research results show that, due to its tight crack width properties compared to ordinary concrete and ordinary fibre reinforced concrete, SHFRCC significantly resists the migration of aggressive substances in to the concrete and improves the durability of reinforced concrete (RC). It is also reported that, due to the strain hardening and multiple cracking behaviours, SHFRCC meets the tight crack width limits for durability of RC structures proposed by different design codes. Based on the reviewed durability properties it is argued that SHFRCC materials can be used in selected locations of RC structural members to improve their overall durability performances.

“…[36,37,38]. The results presented in this paper indicate that fibre reinforcement can also be beneficial in concrete elements with bending cracks, where multiple cracking is not visible at the surface but where branching occurs inside the concrete.…”

In this study, experiments were conducted to induce bending cracks of specific surface crack width to reinforced concrete beams made of plain concrete (RC) and reinforced concrete beams made of fibre reinforced concrete (R/FRC). After injecting and impregnating the cracks with dyed epoxy resin, image processing and analysis were employed to investigate the internal crack morphology. Several crack features including crack width (accumulated, effective and maximum), branching and tortuosity were defined and quantified. The results showed that in addition to arrested crack development, the presence of fibres yielded a distinctive change in the internal crack pattern, including increased branching and tortuosity, both of which have positive implications regarding concrete permeation. Likewise, specimens with fibres exhibited reduced maximum individual crack widths near the rebar, potentially increasing the ability of autogenous crack healing and reducing the risk of corrosion initiation.

“…If such agents reach reinforcing bars, the bars corrode, thus compromising the ability of the structure to withstand loads, which eventually leads to structural failure. Therefore, there has been an interest both in determining the permeability of lightweight concrete compared with normal weight concrete, and in the improvement of this type of concrete with lower permeability [1] .…”

Abstract. This paper was conducted to study the behavior of lightweight concrete, incorporating local lightweight aggregate (LWA), in terms of chloride ion permeability at different ages. The effect of lightweight fine aggregate replacement by normal weight sand (0, 25, 50 and 75% by volume) was investigated. Constant level of silica fume content (10% by weight of cement) as an addition was also considered. Although results showed that the use of porous lightweight aggregate did not lower the permeability of lightweight concrete, test results indicated a decrease in chloride ion permeability as a result of increasing sand replacement for all types of mixes up to 360 days. The reduction in chloride ion permeability was attributed to the presence of the sand which appeared to decrease the porosity of LWC, the reduction in the chloride diffusion coefficient was observed to be as much as 50%. Moreover, the addition of silica fume caused further reductions in chloride ion permeability due to the progression in maturity of LWC, especially after one year of continuous hydration.
