Experimental Research on Mi Xing Concrete Structures Mi Xing Polypropylene Fiber Net

通过14根掺加聚丙烯纤维改善钢筋混凝土梁的试验,研究掺聚丙烯纤维对钢筋混凝土梁的极限承载力的增强效果以及阻裂效果。试验研究表明,掺聚丙烯纤维后,钢筋混凝土梁的极限承载力提高30%左右,试验梁的阻裂性能明显改善。

Through an experiment on improvement of the performance of 14 R.C. beams by mixing polypropylene fibers, the improvement effect of the ultimate bearing capacity and crack resistance of R.C beams after mixing polypropylene fibers were researched. The research result reveals that after mixing polypropylene fibers, the ultimate bearing capacity of R.C beams was improved by 30%. Meanwhile, the crack resistance of the test beams was also improved remarkably.
