“…Diverse fibers such as glass, carbon, aramid, and basalt are utilized in FRP due to their high strength, stiffness, and low-density characteristics [9]. In the field of construction, carbon-fiber-reinforced polymers (CFRP) and glass-fiber-reinforced polymers (GFRP) are widely used due to their robust properties [10,11]. Yet their application is limited in environments requiring high fire resistance standards due to the vulnerability of CFRP composites to degradation at elevated temperatures.…”

Corrosion of conventional steel reinforcement is responsible for numerous structurally deficient bridges, which is a multi-billion-dollar challenge that creates a vicious cycle of maintenance, repair, and replacement of infrastructure. Repair of existing structures with fiber-reinforced polymer (FRP) has become widespread due to multiple advantages. Carbon FRP’s superior tensile strength and stiffness make it particularly effective in shear and flexural strengthening of reinforced concrete (RC) beams. This experimental study incorporates carbon fiber polymer composite bars and wraps to study and report on the flexural behavior of RC beams. By employing a combination of CFRP bar and wrap for strengthening RC beams, this study observed an approximate 95% improvement in flexural load capacity relative to control RC beams without strengthening. This substantial enhancement highlights the effectiveness of integrating CFRP in structural applications. Nevertheless, the key observation is the failure mode due to this combination providing significant insights into the changes facilitated by this combination approach.

Basalt and its reinforcement fibres are highly corrosion resistant, which extends life and lowers production costs while improving shear and flexural strength. Despite the fact that previous study has only concentrated on the mechanical properties of composite fibres. A brief examination was conducted to better understand the reinforced concrete constructions made from basalt and their reinforcements. This study examines deformation; von misses stress, and shear stress performance using the Finite Element Method (FEM). Four different types of natural fibre reinforcing were applied to the RC beams. There are five models like (i) Cement, (ii) Concrete Basalt Fiber + Hemp Fiber + Basalt Fiber, (iii) Concrete + Basalt Fiber + Sisal Fiber + Basalt Fiber, (iv) Concrete + Basalt Fiber + banana Stem Fiber + Basalt Fiber and (v)Concrete + Basalt + Hemp Fiber + sisal Fiber + Banana Stem Fiber + Sugarcane bagasse + Basalt. The RC beam with composites of Basalt Fiber + Sisal Fiber + Basalt Fiber achieves maximum responses. The von misses and shear stress are improved by 1589 MPa and 914 MPa with FEM analysis. Similarly, the FEM analysis was successfully creates the models with higher efficiency. So these fabricated models were suitable for RC beams in the real time applications.
