| 摘 要： | 文中经试配给出了设计强度等级为C20及C40的自密实混凝土配合比。采用MTS实验机获得了棱柱体单轴受压应力-应变本构关系，得到了C20及C40自密实混凝土物理力学性能指标，给出了单轴受压应力-应变关系中峰值应力对应的应变与棱柱体抗压强度之间的关系。通过自密实混凝土试验梁测试结果获得了受压边缘极限压应变，给出了受弯构件混凝土极限压应变与混凝土单轴受压应力一应变关系中峰值应力对应的应变之间的关系。

| Abstract: | Post-built wall beam is wildly used in reconstruction of the existing buildings.Whether the concrete of post-built wall beam can be vibrated to be compact or not is the crucial step.Reinforcement ratio of structural members is relative high in high-rise buildings and long-span buildings,and the "reinforcement densely distributed concrete" members are used in some projects,which bring new requirements for the technique to ensure compactness of concrete.In view of these problems,mixture ratio of design grade ... |
