摘要
介绍了聚丙烯纤维网混凝土桥面铺装设计及施工工艺,综合论述了掺纤维对水泥混凝土力学性能的影响。探讨和分析了聚丙烯纤维水泥混凝土能显著提高混凝土耐磨性、抗冲击能力和抗压、抗折强度,并能降低混凝土的塑性收缩,提高其抗裂能力。
This paper mainly introduces the design and construction of polypropylene fiber grid, discusses the concrete physical influence of adding fiber in general, analyzes the reason why the polypropylene fiber grid can improve the wearability, anti-impact, anti-press, anti-break of the concrete and reduces the concrete plastic shrink ability and anti-crack ability.
