native fiber meaning in English
天然纤维
Examples
- The experiments indicate that polypropylene fiber can efficiently enhance the concrete strength of compression , tension and bending . the concrete strength with addition of fiber made in brazil is higher than that mingled with native fiber under the same water - cement ratio . the strength of concrete with addition of polypropylene fiber is lower than that without fiber under the same slamp value
试验研究表明，聚丙烯纤维能在同水灰比条件下有效改善混凝土的力学性能，提高混凝土的抗压、劈裂抗拉、抗折强度，巴西聚丙烯纤维较国产聚丙烯纤维更能够提高混凝土的抗压、劈裂抗拉、抗折强度。 - Through the investigation on the infiltration and cracking of concrete with addition of polypropylene fibers . the suitable addition of polypropylene fiber to minish the infiltration , crack and autoshrinkage of concrete was gained . the experiments indicate that polypropylene can minish concrete ' s infiltration , cracking and autoshrinkage , and the native fiber is more efficient than that made in brazil . all above proved that it is n ' t right that the finer the polypropylene fiber the better the performance of concrete
试验结果表明聚丙烯纤维能有效改善混凝土的抗渗、抗裂性能并能有效减小混凝土的自收缩，国产聚丙烯纤维在减小混凝土的自收缩、改善混凝土的抗渗、抗裂性能方面更优于巴西聚丙烯纤维，说明了聚丙烯纤维改善混凝土性能并不是越细越好。
