A detailed review on reinforced glass fibre concrete
摘要
Fiber-reinforced concrete (FRC) is concrete reinforced with asymmetric, separated, and uniformly distributed fibers. The fibers are used to increase the flexural, extensible, and impact resistance of reinforced concrete in place of steel reinforcing bars. Fiberglass is currently the preferred material for structural reinforcement since it solves the main issues with steel rebars. In addition to being lightweight, fiberglass textiles feature high stiffness, strength-to-weight ratio, and flexural strength. For specific applications, fiberglass is a material that can be readily molded into complex shapes. Due to the necessity to build high-rise structures, address the deterioration of steel reinforcement over time, and deal with several problems in contemporary construction under the backdrop of growing urbanization, researchers have investigated glass fiber-reinforced concrete in a variety of methods. Fiberglass is much more resistant to chemicals than steel, especially when it comes to corrosion. Usually 75–80% lighter and stronger than steel, fiberglass requires fewer workers to install. To determine the performance of FRC, a variety of tests were carried out, including pullout tests, impact tests, flexural strength tests, shear strength tests, compressive strength tests, split tensile tests, SEM, and XRD analysis. Thus, this study aids in our comprehension of the effects of fiber-reinforced concrete. In conclusion, a more durable, compact, and long-lasting concrete composite can be produced by combining mixed fibers in concrete with a mineral addition like micro-silica. This composite can then be utilized in existing concrete construction to produce stronger and more efficient structures.
