| 2. | A new type of cable gel is introduced , which is used to fill in the interspaces of the cable due to its thermal expansion effects so as to entirely block water intrusion 摘要文章介绍了新一代光缆填充阻水油膏,它的工作机制是利用油膏遇热膨胀的特性将光缆中的空隙填满,从而达到完全隔断水份的目的。 |
| 3. | Bfs can reduce the early strength of high strength superplasticized expansive concrete and make expansion effect develop fully . so high strength concrete with bfs shows higher e2 磨细矿渣的加入使高强膨胀混凝土的早期强度降低,膨胀效应得以较充分发挥,所以加入磨细矿渣的高强混凝土显示出较高的膨胀率。 |
| 4. | In order to meet the market demand , on the base of uea - h , we researched and developed new product - uea - zy in 2001 , which has advantages of low alkali , high expansion effect and good performance of anti - crack and infiltrationproof 为适应市场需要, 2001年,我们在uea h的基础上,研制开发出最新升级产品低碱低掺量高效混凝土剂zy ,该产品碱含量低掺量低,膨胀效能高,抗裂防渗效果好。 |
| 5. | This seemingly contrary phenomenon is rooted in the coordination of expansion and strength development : the high strength especially high early strength of high strength superplasticized expansive concrete confined expansion effect , and there is " self - restricted effect " in concrete 上述看似矛盾的现象源于膨胀混凝土的膨胀与强度的协调性:高强流态膨胀混凝土的高强度,特别是较高的早期强度限制了膨胀效应的发挥,在混凝土内部存在“自约束效应” 。 |
| 6. | The results of experiment on the relationship between tensile strength , shrinkage , self - desiccation shrinkage and flat restraint cracking show that sra ' s physical shrinkage - reducing effect and ea ' s chemical expansion effect greatly enhance the volume stability of concrete and reduce the probability of early - cracking 对减缩剂与膨胀剂抗拉强度、干缩、自干燥收缩及平板约束开裂的试验结果表明: sra的物理减缩作用及膨胀剂的化学膨胀作用,大大提高了混凝土早期的体积稳定性,降低了早期开裂的概率。 |
| 7. | From the research on hpec we can know that expansion property of high strength superplasticized expansive concrete shows obvious particularity compared with ordinary expansive concrete . when bfs is not put in , high strength superplasticized expansive concrete shows autogenous shrinkage in 1 day standard curing . and in 14 day ' s age e2 is less than half of middle strength superplasticized expansive concrete ' s with same csa dosage , and this shows expansion effect is confined more 对hpec混凝土的研究发现,与普通膨胀混凝土相比,高强流态膨胀混凝土的膨胀性能表现出明显的特殊性,在不掺超细矿物质掺合料(磨细矿渣)时,高强流态膨胀混凝土标准养护1天时出现自收缩, 14天时其限制膨胀率不到相同csa掺量的中强流态膨胀混凝土限制膨胀率的一半,表现为膨胀效应受到更大限制。 |
