掺玻璃纤维和聚丙烯纤维混凝土力学性能分析

Analysis of mechanical properties of Glass Fiber and Polypropylene Fiber reinforced concrete

将玻璃纤维(GF)和聚丙烯纤维(PPF)按不同含量掺入混凝土中,并进行抗压、抗折试验。对试验结果进行分析,从而得出添加GF和PPF可以提高混凝土抗折强度、降低抗压强度,不同种类含量和配合比的试验结果稍有差异,但不显著,掺入GF提高抗折强度幅度最高,与此同时抗压强度降低幅度也最明显,双掺纤维力学性能居中。

Glass Fibers（GF）and Polypropylene Fibers（PPF）were blended into concrete in different contents and subjected to compression and flexural tests.The analysis of the test results shows that the addition of GF and PPF can improve the flexural strength of concrete and reduce the compressive strength,but the test results of different types of content and mix ratio are slightly different,but not significant.Incorporation of GF increased the highest flexural strength,while the compressive strength decreased most significantly.The mechanical properties of the doubledoped fiber are intermediate.
