| 1. | Shrinkage of concrete 混凝土的收缩 |
| 2. | Shrinkage strains are mdependent of the stress conditions in the concrete 混凝土的收缩是一种自发的变形,并不依靠作用在混凝土上的外力。 |
| 3. | Research on compensating shrinkage of high strength concrete incorporated with expansive admixture 引入膨胀剂的高强混凝土的收缩补偿研究 |
| 4. | Therefore , how to compensate for its shrinkage has become an unavoidable and important problem that limits its utilization 如何补偿超高强混凝土的收缩,成为制约其应用和发展的一个不可回避的重要课题。 |
| 5. | The main research contents are as follows : 1 . this thesis observes the shrink and creep curve of plain concrete and concrete filled steel tubes 主要研究内容如下: 1 、观测得到素混凝土及钢管混凝土的收缩(膨胀)徐变曲线。 |
| 6. | Hence , in order to guarantee the engineering quality , we must reduce the concrete shrink and creep furthest in constructing and design 因此在预应力混凝土结构的设计和施工中,应尽量减少混凝土的收缩和徐变,保证工程质量。 |
| 7. | Further more , the prestress loss , which is caused by the shortened beam member due to concrete shrink and creep , is of disbenefit to prestress concrete structure 不仅如此,混凝土的收缩和徐变使构件缩短而引起预应力损失,对预应力混凝土结构十分不利。 |
| 8. | This paper expounds the shrinkage effect and temperature effect of the concrete , and advances some measures for controlling the cracks of the concrete in the construction practice 阐述了混凝土的收缩作用和温度作用,并提出了在工程实践中进行裂缝控制的措施。 |
| 9. | The influence of mineral materials such as fly ash , blast furnace slag and silica fume on expansion performance of the common concrete and compensating - shrinkage concrete was researched 在此基础上,研究了高强混凝土在不同龄期的收缩规律,发现高强混凝土的收缩特性与普通混凝土存在显著不同。 |
| 10. | But be the concrete to transform the stipulation ( repress , bar ) function , then want the companion to living to pull in response to the dint with pull to adapt to changes 混凝土随着温度、湿度的变化要伴生胀缩变形。而当混凝土的收缩变形受到约束(抑制、阻碍)作用时,则要伴生拉应力和拉应变。 |
