摘要
对聚乙烯醇纤维增强水泥基复合材料棱柱体试件进行了抗折试验,并对抗折试验后的一半试件进行了抗压试验。试验结果表明,随PVA纤维掺量的增加,试件抗折强度大幅提高,抗压强度先略有提高然后降低,纤维在水泥基体中起到了很好的增韧效果。
The bending tests were carried out on the prism specimens of PVA fiber reinforced cement based composite materials, and the compressive tests were carried out on the half of the bending test specimens. The test results show that with the increasing of PVA fiber content, the bending strength of the specimen has an obvious increasing, but the compressive strength of the specimen increase slightly first and then decrease. The fibers in the cement matrix play a toughening role.
