聚丙烯纤维与废胶粉混杂砼抗拉抗折性能研究

本文通过对28天龄期的废旧轮胎胶粉与聚丙烯纤维混杂混凝土的抗拉、抗折强度等力学性能试验研究，得出初步结论：混杂混凝土，比相同掺量的单一胶粉混凝土的抗拉、抗折性能有所提高，并具有极好的强度恢复性能。混杂混凝土抗折强度掺量为5%时强度最大，10%时又出现下降趋势。

Study of Polypropylene fiber and Waste Arubber Powder Hybrid strength to Tensile and Flexural

This article through to 28 days powder and waste tires of polypropylene fiber mixed concrete tensile strength, flexural strength and mechanical properties such as experimental study concluded, preliminary conclusions: mixed concrete admixture than the same single powder concrete tensile strength, flexural performanc im eproved, and have excellent strength restore performance. Mixed concrete flexural strength for the admixture of 5%, 10% are most strong decline appear again.
