几种纤维对透水混凝土抗冻性影响综述

Influence of several fibers on frost resistance of pervious concrete

近年来,透水混凝土得到了广泛应用,但在寒冷地区,抗冻性是影响其使用的重要性能。通过查阅相关资料,综述了不同纤维种类及掺量对透水混凝土抗冻性的影响。结果表明,几种纤维均能提高透水混凝土抗冻性能,且随着纤维掺量的增加,透水混凝土抗冻性提高,但每种纤维都有适合的掺量,掺量太大反而不利于抗冻性的提高。

In recent years,pervious concrete has been widely used,but in cold areas,it’s using is affected by the freezing resistance.The influence of different fiber types and dosage on frost resistance of pervious concrete was summarized in this paper.The results showed that several kinds of fiber could improve the frost resistance of pervious concrete,and with the increase of fiber dosage,the frost resistance of pervious concrete was improved,but there was a suitable content for each fiber,too much content is not conducive to the improvement of frost resistance.
