“…In addition, in Figure 1, the cross-sections of these bars are shown. The test results were compared with GFRP bars [23]. Furthermore, the modulus of elasticity of composite hybrid bars was compared with the modulus of elasticity obtained from theoretical relationships.…”

One of the main disadvantages of steel bars is rebar corrosion, especially when they are exposed to aggressive environmental conditions such as marine environments. One of the suggested ways to solve this problem is to use composite bars. However, the use of these bars is ambiguous due to some weaknesses, such as low modulus of elasticity and linear behavior in the tensile tests. In this research, the effect of the hybridization process on mechanical behavior, including tensile strength, elastic modulus, and energy absorbed of composite bars, was evaluated. In addition, using basalt fibers because of their appropriate mechanical behavior, such as elastic modulus, tensile strength, durability, and high-temperature resistance, compared to glass fibers, as the main fibers in all types of composite hybrid bars, was investigated. A total of 12 hybrid composite bars were made in four different groups. Basalt and carbon T300 composite fibers, steel bars with a diameter of 6 mm, and steel wires with a diameter of 1.5 mm were used to fabricate hybrid composite bars, and vinyl ester 901 was used as the resin. The results show that, depending on composite fibers used for fabrication of hybrid composite bars, the modulus of elasticity and the tensile strength increased compared to glass-fiber-reinforced-polymer (GFRP) bars by 83% to 120% and 6% to 26%, respectively. Moreover, hybrid composite bars with basalt and steel wires witnessed higher absorbed energy compared to other types of hybrid composite bars.

“…The second method is to enhance the properties of concrete in such a way that it has less permeability. This method can be referred to as using additives to concrete such as pozzolans [16][17][18][19][20][21] or reducing the ratio of water to cement in the concrete mixing design [9,22,23].…”

“…180 C-S-H is a non-stoichiometric compound related to the mechanical properties of cement, such as strength, shrinkage and durability, and are responsible for most of these properties. 25 In the literature, many studies deal with the pozzolanic activity of minerals, in composite materials reinforced natural fibers, such as lime, 147 metakaolin, 181,182 silica fume 183 or fly ash. 184 Various types of biomasses or wastes of agro-industrial processes, produced ash which can have a pozzolanic activity and can be used as partial replacement of cement: rice husk ash, 185 palm oil ash, 186 sugarcane bagasse ash 28 or corn straw ash 187 ; 147 Table 18 presents some researches about the effect of the replacement of cement by pozzolanic-like compounds in vegetable fibers reinforced cementitious composites.…”

This paper presents some principles of research done on the assessment of fiber-matrix adhesion and durability in cement-based and polymer-based composites reinforced with vegetable fibers. Natural vegetable fibers are light, biodegradable and low-cost; however, their compatibility with both matrices - which are generally hydrophobic- is poor, because of their hydrophilic character. This review presents the different strategies proposed in literature to improve (1) interfacial bonding between matrix and fibers and (2) sustainability of composite materials reinforced by vegetable fibers. In order to achieve these goals, searchers investigate chemical or/and physical treatments of fibers and/or matrix modification of composites materials. The impacts of these strategies are followed in terms of mechanical properties, thermal properties, morphology and water absorption of the composite materials. Authors proposed to focus on the influence of aging on these characteristics in order to estimate durability.

“…Similarly, samples with bers demonstrated poorer permeability than samples without them in (Kakooei et al 2012). There have also been studies that show that permeability declines as the volume of bers grows up to a certain point, then increases and sometimes exceeds that of plain concrete (Flores Medina et al 2015). This is usually due to a lack of workability and an excessive amount of bers in the mixture.…”

This research presents a new method for determining the impact of healthy personal protection materials HPPM stripes, such as surgical masks, protective suits, overhead and safety foot shoes, on the durability, physicomechanical characteristics of concrete for use in architectural forms. As a result of the current global epidemic caused by Coronavirus, the use of (HPPM) such as surgical masks, protective suits, overhead and safety foot shoes has increased considerably (COVID-19). COVID-19's second and third waves are currently affecting various countries, necessitating the use of face masks (FM). As a result, millions of single FS have been discharged into the wild, washing up on beaches, floating beneath the seas, and winding up in hazardous locations. The effect of stripes fibers on physicomechanical aspects of concrete, such as workability, UCS, FS, IMs, spalling, and AbR; sorptivity, Sw; n; water penetration, permeability, and economic and eco-friendly aspects, was also discussed. With a focus on HPPM especially single-use face masks, this research investigates an innovative way for incorporating pandemic waste into concrete structures. SEM and XRD were also employed to analyze microstructures and the interfacial transition zone, as well as to identify the elements. HPPM was found to have a pore-blocking effect, which reduced permeability and capillary porosity. It was also discovered that the best concentrations of HPPM, particularly masks, were applied by volume at 0 %, 0.1, 1.5, 2.0, and 2.5 %. The usage of single-use face masks increased the strength qualities and overall performance of the concrete samples. The tendency of growing strength began to disappear around 2%. The results of this investigation show that stripe content has no effect on compressive strength. The stripe, on the other hand, is critical in determining the flexural strength of concrete. A SEM was used to analyze the microstructure of concrete. HPPM fibers are discovered to act as bridges across cracks, enhancing the matrixes transfer capability. From a technological and environmental standpoint, the study found that using healthy personal protection materials fiber in the production of concrete is viable.
