Preparation method of rigid polymer fiber for concrete crack resistance and capable of improving impact energy consumption
The invention discloses a rigid polymer fiber for concrete crack resistance and capable of improving impact energy consumption. The rigid polymer fiber comprises the following raw materials in parts by weight: 40-60 parts of a reinforcing material, 10-15 parts of polypropylene, 8-15 parts of synthetic resin and 3-8 parts of an auxiliary agent. The invention further provides a preparation method of the rigid polymer fiber capable of improving impact energy consumption and used for concrete crack resistance. By adding the high-strength glass fibers, the basalt fibers and the ultrahigh relative molecular weight polyethylene fibers, the rigidity and the anti-cracking performance of the concrete can be improved when the concrete is used in the concrete.
本发明公开了一种提高冲击耗能的混凝土抗裂用刚性聚合纤维，其原料按照重量份数计配方如下：增强材料40‑60份、聚丙烯10‑15份、合成树脂8‑15份、辅助剂3‑8份。本发明还提出了一种提高冲击耗能的混凝土抗裂用刚性聚合纤维制备方法。本发明通过添加高强玻璃纤维、玄武岩纤维和超高相对分子质量聚乙烯纤维，用在混凝土中时，能够提高混凝土的刚性和防裂性能。
