| 摘 要： | 通过不同钢纤维含量活性粉末混凝土的拉伸性能试验,测定活性粉末混凝土的劈裂抗拉强度、轴心抗拉强度及轴心受拉应力-应变全曲线.研究钢纤维体积率对活性粉末混凝土劈裂抗拉强度、轴心抗拉强度的影响规律.研究表明,随着钢纤维掺量的增加,活性粉末混凝土的劈裂抗拉强度、轴心抗拉强度呈线性增大规律;给出活性粉末混凝土轴心抗拉强度和劈裂抗拉强度的关系;提出活性粉末混凝土轴心受拉应力-应变全曲线的数学模型,并根据试验结果确定模型参数.研究成果可为活性粉末混凝土在结构中的应用提供依据.

| Abstract: | The experimental study on the performance of reactive powder concrete(RPC) with different steel fiber ratios were developed.The splitting tensile strength,axial tensile strength and axial tensile stress-strain curve of RPC were measured.The effects of the steel fiber volumetric ratio on the splitting tensile strength and axial tensile strength were studied.The results indicate as follows: Both the splitting tensile strength and axial tensile strength of RPC increase with the increasing of the steel fiber vo... |
