研究黄麻纤维在纤维掺量、纤维长度及混杂纤维配合比不同的情况下分别对砂浆早期抗裂性能的影响，并与聚丙烯腈纤维作对比研究。试验结果表明：黄麻纤维能有效地增强砂浆的早期抗裂性能，并随着纤维掺量的增加、纤维长度的减小以及混杂纤维中起主要作用的黄麻纤维含量的增加而增强；黄麻纤维对砂浆早期抗裂性能的增强效果不及聚丙烯腈纤维。

The early cracking resistance of jute fiber reinforced mortar with different volume , different length and different mixing ratio of hybrid fibers was studied , and a comparative study with polyacrylonitrile fiber was carried out .The experimental results show that jute fiber can improve the early cracking resistance of mortar effectively , and the reinforcing effect is improved with the increase of fiber volume , the decrease of fiber length and the increase of jute fiber content in all the fibers .The reinforcing effect of jute fiber on the early cracking resistance of mortar is not as good as that of polyacrylonitrile fiber .
