摘要：研究表明纤维极大地提高了混凝土的性能。文献确定钢纤维可以提高水泥基复合材料的弯曲强度和能量吸收能力。然而，由钢纤维组成的混凝土公路在腐蚀条件下消除了纤维的影响。因此，高分子纤维生产商推出了能够承受腐蚀环境和化学品的纤维，并推出了聚酯和聚丙烯纤维来替代钢纤维。本研究旨在确定由聚酯纤维、聚丙烯纤维和钢纤维组成的混凝土与传统混凝土的性能对比。因此，用 0%、1% 和 2% 生产的混凝土混合物的新拌混凝土和硬化混凝土性能是通过实验室测试确定的。通过分别对 150x150x150 mm 立方体和 100x100x500 mm 棱柱形试件进行抗压强度和抗拉强度测试，研究了这些混凝土试件的力学性能。路面混凝土的耐磨性是通过对70x70x70毫米立方体试件进行Bohme磨损试验来测量的。测试结果表明，纤维可以增强混凝土抵抗刚性路面使用寿命期间可能发生的外部影响。聚合物纤维添加剂在混凝土耐磨性和混凝土机械性能方面取得了重大进展。
Abstract: Researches demonstrate that fibers boost performance of concrete incredibly. It’s determined that in literature steel fibers increase flexural strength and energy absorption capacity of the cementitious composites. However concrete highways consist of steel fibers in corrosive conditions eliminate fiber’s effect. Therefore producers of polymeric fibers launch fibers which can withstand corrosive environments and chemicals, and launch polyester and polypropylene fibers alternative to steel fibers. This research intends to determine the performance of concretes consist of polyester fiber, polypropylene fiber and steel fiber against traditional concrete. For this reason, fresh and hardened concrete properties of the concrete mixtures produced with 0%, 1% and 2% are determined by laboratory tests. The mechanical behaviors of these concrete specimens are investigated by compressive strength and tensile strength tests on 150x150x150 mm cubic and 100x100x500 mm prismatic specimens respectively. The abrasion resistance of the pavement concrete is measured by Bohme abrasion test on 70x70x70 mm cubic specimens. Test results showed that fibers are reinforced concrete against external effects which can be occurred during the service life of the rigid pavements. Significant developments are determined with the polymer fiber additives on concrete abrasion resistance and mechanical behavior of concrete.
