| 中文摘要: |
| 水泥在常温下可以正常水化，但在负温下水化及强度的发展都受到了一定的抑制。实验研究了水泥在负温环境下的强度发展规律，结果表明：在恒负温环境下养护时间的延长对水泥后期强度的增加有一定影响但意义不大；自然变负温环境下养护时间对水泥后期强度发展的影响具有重要意义，后期强度基本可以达到标准水平。 |
| 英文摘要: |
| Normal hydration of cement can proceed at room temperature, but at negative temperature, the development of hydration and strength of the cement is inhibited. The experiment researched on the development of cement strength under negative temperature, the results indicate that increasing curing time has a little effect on the later strength of cement,but there is no much meaning; and curing time has a great significance on the later strength of cement under natural varied minus-temperature, the strength can basically reach the normal level. |
