| 中文摘要: |
| 利用自行设计的杠杆卧拉式徐变测定装置对早龄期掺外加剂混凝土进行徐变特性试验研究,研究外加剂对于混凝土早期徐变特性的影响。研究表明,缓凝、泵送混凝土增强剂对混凝土早期拉伸徐变有一定的影响,在同水灰比及水泥用量条件下,加载时混凝土强度越低,徐变越大。 |

| Experimental research on creep characteristics of early age concrete which mixed admixtures by using self-designed leveraged creep device.Research on Influence of admixtures for early creep characteristics of concrete.Studies have shown that retardation,pumping concrete reinforcing agent have a certain influence on early tensile creep of concrete.Under the conditions of the same amount of water-cement ratio and cement,the lower concrete strength,the higher concrete creep,when it comes to loading. |
