Prior studies in the literature show promising results regarding the improvements in strength and durability of concrete upon incorporation of glass fibers into concrete formulations. However, the knowledge regarding glass fiber usage in concrete is scattered. Moreover, this makes it challenging to understand the behavior of glass fiber-reinforced concrete. Therefore, a detailed review is required on glass fiber-reinforced concrete. This paper provides a compressive analysis of glass fiber-reinforced composites. All-important properties of concrete such as flowability, compressive, flexural, tensile strength and modulus of elasticity were presented in this review article. Furthermore, durability aspects such as chloride ion penetration, water absorption, ultrasonic pulse velocity (UPV) and acid resistance were also considered. Finally, the bond strength of the fiber and cement paste was examined via scanning electron microscopy. Results indicate that glass fibers improved concrete's strength and durability but decreased the concrete's flowability. Higher glass fiber doses slightly decreased the mechanical performance of concrete due to lack of workability. The typical optimum dose is recommended at 2.0%. However, a higher dose of plasticizer was recommended for a higher dose of glass fiber (beyond 2.0%). The review also identifies research gaps that should be addressed in future studies.
文献中先前的研究表明，在混凝土配方中加入玻璃纤维后，混凝土的强度和耐久性有所提高，结果很有前景。然而，关于玻璃纤维在混凝土中的使用知识较为分散。此外，这使得理解玻璃纤维增强混凝土的性能具有挑战性。因此，需要对玻璃纤维增强混凝土进行详细的综述。本文对玻璃纤维增强复合材料进行了全面分析。这篇综述文章介绍了混凝土的所有重要性能，如流动性、抗压强度、抗弯强度、抗拉强度和弹性模量。此外，还考虑了耐久性方面，如氯离子渗透性、吸水性、超声脉冲速度（UPV）和耐酸性。最后，通过扫描电子显微镜检查了纤维与水泥浆体的粘结强度。结果表明，玻璃纤维提高了混凝土的强度和耐久性，但降低了混凝土的流动性。由于工作性不足，较高剂量的玻璃纤维会略微降低混凝土的力学性能。建议典型的最佳剂量为2.0%。然而，对于较高剂量的玻璃纤维（超过2.0%），建议使用更高剂量的增塑剂。该综述还指出了未来研究中应解决的研究空白。
