摘要
文章介绍了低掺率聚丙烯纤维混凝土的抗裂和抗渗性能。通过和普通混凝土对比后得出结论:低掺率的聚丙烯纤维能有效提高混凝土的限裂和抗渗能力,改善钢筋混凝土蜗壳的抗渗效果,说明了聚丙烯纤维对大级配混凝土的适应性。
The paper introduces the anticlastic and water-tight performance of low content polypropylene fibre concrete.The comparison between .his concrete and the normarl concrete indicates that this concrete effectively raises the anticlastic and water-tight performance of concrete, improves the impervious effect of reinforced concrete spiral easing, it indicates that the polypropylene fibre adapts the large gradation concrete.
