| 中文摘要: |
| 以有机聚丙烯纤维为对比，进行了无机玄武岩纤维水泥砂浆的抗压、抗折、抗拉伸及抗弯系列力学性能试验研究。研究结果表明：在最佳掺量下，玄武岩纤维水泥砂浆的各种力学性能优于聚丙烯纤维水泥砂浆；玄武岩纤维对水泥浆体早期具有显著的增强作用，但降低了水泥砂浆的28d强度；掺入玄武岩纤维可以增加砂浆的韧性，对砂浆的抗拉强度改善起到了一定作用；玄武岩纤维对砂浆的抗弯破坏强度改善不显著，但明显增大了相同荷载下试件的挠度。 |
| 英文摘要: |
| Compared with the polypropylene fiber (PP),the effect of basalt fiber (BF) on compressive,flexural,tensile, bending strength of cement mortar were studied and discussed. The results show that mechanical properties of BF cement mortar are better than those of PP cement mortar at the optimum addition respectively. The addition of BF into cement mortar have a greater compressive and flexural strength than blank at earlier period,but had a bad influence in 28d compressive and flexural strength of cement mortar.... |
