聚丙烯纤维对现浇混凝土板抗裂性能影响的试验研究

Crack resistance of polypropylene fiber concrete slab experimental study

通过掺入聚丙烯纤维到现浇混凝土板中进行试验,分析研究了聚丙烯纤维对现浇混凝土板抗裂性能的影响。试验结果表明,掺一定量的聚丙烯纤维对现浇混凝土板的抗裂性能有很大提高,在相同龄期下,现浇混凝土平板的裂缝降低率会随着聚丙烯纤维掺入量的增加而提高,可解决或缓解混凝土容易开裂的问题。

By incorporating a certain amount of polypropylene fibers to conduct in-situ concrete slab treadmill test,the influence of polypropylene fiber on the in-situ concrete slab crack resistance is analyzed. Experimental results show that a certain amount of polypropylene fibers doped cast concrete panels on the crack resistance is greatly improved,in the same period,the in-situ concrete slab with cracks will reduce the rate of incorporation of polypropylene fibers with increasing of polypropylene fiber concrete cracking so as to solve or alleviate the problem of concrete cracking easily.
