“…The newly developed basalt microfibers are added longitudinally as reinforcement to the concrete structures to study its feasibility and flexural behavior; it exhibits improvement in curvature ductility with increased maximum moment capacity of the beams. Regardless of the type of concrete used, there is an enhancement in the flexural capacity of the beams with an increase in BFRP reinforcement ratio [180,181,182]. Figure 13a shows some RC beams.…”

Composites have been found to be the most promising and discerning material available in this century. Presently, composites reinforced with fibers of synthetic or natural materials are gaining more importance as demands for lightweight materials with high strength for specific applications are growing in the market. Fiber-reinforced polymer composite offers not only high strength to weight ratio, but also reveals exceptional properties such as high durability; stiffness; damping property; flexural strength; and resistance to corrosion, wear, impact, and fire. These wide ranges of diverse features have led composite materials to find applications in mechanical, construction, aerospace, automobile, biomedical, marine, and many other manufacturing industries. Performance of composite materials predominantly depends on their constituent elements and manufacturing techniques, therefore, functional properties of various fibers available worldwide, their classifications, and the manufacturing techniques used to fabricate the composite materials need to be studied in order to figure out the optimized characteristic of the material for the desired application. An overview of a diverse range of fibers, their properties, functionality, classification, and various fiber composite manufacturing techniques is presented to discover the optimized fiber-reinforced composite material for significant applications. Their exceptional performance in the numerous fields of applications have made fiber-reinforced composite materials a promising alternative over solitary metals or alloys.

“…Figure 11 also shows the impact of increasing reinforcement ratio on the ultimate moment. The impact of increasing the reinforcement ratio does not result in directly proportional increase in the ultimate moment, as shown in [ 11 ]. For example, when the reinforcement ratio of 0.0034 (2T8BE) is increased to 0.0073 (2T12BE), the 115% increase only yields a 32% increase in the ultimate moment capacity (from 21.7 to 28.7 kN·m).…”

“…Few studies investigated the mechanical behavior [ 5 ], compression behavior [ 6 ], shear behavior [ 7 , 8 , 9 , 10 ], and flexural behavior [ 11 , 12 , 13 , 14 , 15 ] of BFRP reinforcement. Elgabbas et al [ 11 ] studied the behavior of FRP reinforced concrete beams subjected static loading. The study indicated that an increase in reinforcement ratio led to a nonlinear increase in the flexural capacity of FRP reinforced concrete beams.…”

The main objective of this study was to investigate experimentally and numerically the behavior of basalt fiber-reinforced polymer (BFRP) reinforcement exposed to a combination of ultraviolet rays, humidity, and rain. Specifically, the effects of the previously stated harsh exposure on the serviceability performance and flexural capacity of BFRP reinforced concrete beams was examined. Holding the exposure parameter constant, the study also evaluated the effects of reinforcement ratio and beam detailing on the flexural capacity and the bond-dependent coefficient (kb) of the beams. Seven beams were cast and tested, four of which were reinforced with exposed BFRP bars, two were reinforced with unexposed BFRP bars, and one specimen was cast and reinforced with steel bars to serve as a benchmark specimen. The results indicate that the kb factor was averaged to be 0.61 for all the beams. Test results also indicate that increasing the reinforcement ratio did not result in a directly proportional increase in the moment capacity. The period of exposure did not cause any significant impact on the behavior of the over-reinforced beams. Thus, a finite element model was created to simulate the impact of exposure on the behavior of under-reinforced BFRP reinforced concrete beams.

“…Fiber reinforced polymer (FRP) composite materials have attracted growing attentions to be the building materials due to the superior corrosion resistance (Micelli and Nanni, 2004;Miyano et al, 2005;Correia et al, 2015;Sankholkar et al, 2018). For example, FRP reinforcements have been used to replace the normal steel bars in some RC structures (Chen et al, 2007;Benmokrane et al, 2017;Elgabbas et al, 2017). By this way, the durability of the RC structures could be apparently improved, especially in the marine engineering and the hydraulic engineering.…”

Glass fiber reinforced polymer (GFRP) pultruded rectangular tubes were used externally to confine Reinforced Concrete (RC) beams in this experimental study, aiming to improve the corrosion resistance of the RC beams in the harsh environment (e.g., Hydraulic structures and Marine structures). The flexural behavior of the composite beams reinforced with GFRP tubes was investigated by using four-point bending test. The experimental program involved the testing of six beam specimens reinforced with or without the GFRP tubes, and the main parameters investigated included the reinforcement ratio of the tensile steel bars and the stirrup spacing. The experimental results show that the flexural strength and stiffness of the RC beam members were significantly improved by using the GFRP tubes. The brittle failure of the beam specimens was caused by the local failure at one loading pints on the top flange of the GFRP tubes. The higher reinforcement ratio of the tensile steel bars contributed to the improvement of the flexural strength and bending stiffness. The stirrup spacing had little effect on the flexural behavior of the beam specimens in the proposed composite beams.
