摘要：

深入探究纤维增强聚合物混凝土(FRPC)在道路工程材料领域的性能表现. 通过系统试验,研究了不同纤维类型(碳纤维、玻璃纤维)、纤维掺量以及纤维长度对聚合物混凝土抗压强度、抗拉强度、抗弯强度和耐久性等性能的影响. 结果表明,纤维的加入显著提升了聚合物混凝土的各项性能,但不同纤维种类和参数的影响效果存在差异. 基于试验结果,提出了针对性的性能优化策略,为 FRPC 在道路工程中的广泛应用提供了理论依据和实践指导.

The purpose of this study is to investigate the performance of fiber reinforced polymer concrete(FRPC) in the field of road engineering materials. The effects of different fiber types ( carbon fiber,glass fiber), fiber content and fiber length on compressive strength, tensile strength, flexural strengthand durability of polymer concrete were studied through systematic tests. The results show that theaddition of fiber significantly improves the properties of polymer concrete, but the effects of different fibertypes and parameters are different. Based on the test results, a specific performance optimization strategyis proposed, which provides theoretical basis and practical guidance for the wide application of FRPC inroad engineering.
