| 摘 要： | 为进一步提高PPC的力学性能，满足国防工程的需要，进行了不同掺量钢纤维的情况下水泥基复合材料的力学性能试验。试验测得了不同钢纤维含量的情况下，水泥的各种强度。试验表明，在钢纤维体积率相同的情况下，抗折强度的提高率要大于劈拉强度的提高率，但钢纤维体积率超过一定比例后抗折强度与劈拉强度的提高率变小。随钢纤维体积率的增加，钢纤维水泥净浆的抗压强度也有所增大，但提高并不明显。并对以上试验结果做了分析，认为纤维间距是影响强度的重要原因。

| Abstract: | In order to enhance the mechanics capability of RPC, the tests on the cement steel fiber reinforced cement-base composites with different steel fiber bulk ratio were carried out. Many kinds of strengths of the cement with different steel fiber bulk ratios are obtained. The results show that the enhanced ratio of bending strength is more than that of cleavage strength with the same steel fiber bulk ratio, but the strengths enhance slower when the ratio reach the some percent. The compressive strength is also higher with the increase of steel fiber bulk ratio, which is not apparent. The causations are analyzed that the distance between fibers have the important influence on the strength. |
