混杂纤维混合物砂浆力学性能分析

On dynamic performance analysis of hybrid fiber mixed mortar

通过混杂玻璃纤维和聚丙烯纤维,试验研究了混杂纤维增强水泥砂浆的抗压、抗折及压折比性能,结果表明,添加纤维可增强砂浆抗折强度;三个纤维掺量中,2%玻璃纤维掺量的抗折强度最高,并可减小砂浆压折比,较不掺纤维的水泥砂浆表现出一定的优势。

According to the experimental research on the glass fiber and polypropylene fiber, the paper researches the compressive performance, fracture rebamboo compissistance and ratio of compressive strength of the hybrid fiber reinforced cement mortar, and proves by the result that the added fiber can enhance the fracture resistance of the mortar, and its fracture resistance reaches the highest with 2 % mixture of the glass fiber a- mong the three fiber mixing volumes, and it can also reduce the ratio of the compressive strength of the mortar, so it has certain advantages by comparing with other cement fibers with other fibers.
