聚丙烯纤维混凝土路用性能研究

The Study of the Road Preformance of the Polypropylene Fiber Concete

本文研究了聚丙烯纤维混凝土的路用性能，论述了聚丙烯纤维对道路混凝土的强度、脆性、抗渗性。耐磨性以及温度收缩与弹性模量等性能的影响，探讨和分析了聚丙烯纤维改善混凝土性能的机理。试验结果表明，道路混凝土中掺入纤维能明显降低混凝土的脆性，提高混凝土的抗折强度和耐磨性能。

In this paper, the road performance of polypropylene fiber concrete in studied, the influence of the polypropylene fiber on the strength, brittleness, premeability resistance, abrasion resistance, tenperature shrindage and elastic madule of the concrete are discussed and the mechanism which polypropylene fiber can inprove the concrete is also analyzed. Test and analysis results indicate that mixing fiber into road concrete can decrease the brittleness and promote the flexural strength and abrasion resistance.
