“…The critical concentration of chloride ion for the steel fiber whose diameter is in the range of 0.99 mm ~1.18 mm is an order of magnitude, which is obviously higher than that of traditional steel bars [18] . The critical chloride ion mass of the steel fiber accounts for 0.8%~1.0% of cement mass determined by curve interpolation [19] , and the upper and lower limits are both higher than the steel bars (0.4%~0.6%) [20] .…”

Chloride ions, water, and oxygen could cause the corrosion of steel fiber in the aggressive environment. The corrosion of steel fiber in UHPC is a long-term process and the rate is very slow. As one of the important components of ultra-high performance concrete (UHPC), the corrosion of steel fiber is the result of multiple factors. The characteristics of steel fiber corrosion in UHPC, the factors influencing the corrosion of steel fiber in UHPC (including nanomaterials, curing condition and crack width), and effects of steel fiber corrosion on the UHPC performance (including mechanical properties, matrix rehydration and corrosion of steel bar), are emphatically elaborated. And the control methods of steel fiber corrosion in UHPC are briefly introduced, i.e. hybrid fibers and stainless steel fibers.

TiO2 nanotubes were successfully synthesized by electrochemical method. A fluoride salt mixture was used as an electrolyte for synthesizing TiO2 nanotubes on titanium substrates. In this work, we have reported the synthesis procedure of TiO2 nanotubes and investigated the corrosion resistance of TiO2 nanotubes coated on the Ti substrate. FE-SEM was used to observe the morphology and determine the size of the TiO2 nanotubes. The phase formation and crystal quality of TiO2 nanotubes were studied by XRD measurements. One-microliter distilled water droplets were used to define the wettability of the TiO2 nanotube surfaces by measuring the contact angle. The corrosion resistance behavior of specimens was analyzed in the simulated body fluid solution (SBF) using potentiodynamic polarization tests for potential application as implants.

“…Liu et al [ 161 ] applied a zinc phosphate conversion coating to steel fibers and test them via SEM and XRD under high temperatures to assess corrosion. The fibers showed effective results up to 75 °C; however, they became less effective when the temperature rose beyond 85 °C.…”

A Comprehensive Analysis of the Use of SFRC in Structures and Its Current State of Development in the Construction Industry

In recent years, concrete technology has advanced, prompting engineers and researchers to adopt advanced materials to improve strength and durability. Steel-fiber-reinforced concrete (SFRC) represents the substantial modification of concrete materials to improve their structural properties, particularly their flexural and tensile strength. Whether SFRC is stronger than conventional concrete depends on a variety of variables, including the volume, size, percentage, shape, and distribution of fibers. This article provides a comprehensive discussion of the properties of SFRC, such as durability, fire resistance, and impact resistance or blast loading, as well as the application of SFRC in structural members including beams, columns, slabs, and walls. The application of steel fibers in various types of concrete, including pre-stressed, pre-cast, self-compacting, and geopolymer concrete, was also examined in this comparative analysis review, and recommendations for the future scope of SFRC were identified.
