玻璃纤维与聚丙烯纤维混凝土的抗压性能分析

Compressive performance analysis of glass fiber and polypropylene fiber reinforced concrete

在混凝土中掺入不同量的玻璃纤维和聚丙烯纤维,设置三组不同水灰比试验进行立方体抗压试验,试验结果表明,玻璃纤维对混凝土立方体抗压强度有一定的提高作用,聚丙烯纤维对强度提高作用不明显。水灰比较大时,两种纤维混凝土强度下降明显。

The cubic compressive test was carried out by mixing different amounts of glass fiber and polypropylene fiber into concrete and setting up three groups of tests with different water cement ratio. The results show that glass fiber can improve the cubic compressive strength of concrete to a certain extent,while polypropylene fiber has no obvious effect on the strength. When the water cement ratio is larger,the strength of the two kinds of fiber reinforced concrete decreases obviously.
