| 摘 要： | 以水灰比为0.60,0.55,0.50,0.45和0.40的普通混凝土抗冻耐久性为研究内容,用混凝土相对动弹性模量和质量损失率来表征冻融过程中性能劣化状况.通过试验得出：随着冻融循环次数的增加,相对动弹性模量基本上呈直线变化,而质量损失率在循环初期,随水灰比不同,呈不同变化趋势,后期质量都减小.

| 关 键 词： | 冻融循环 质量损失率 相对动弹性模量 |

| Abstract: | The freeze-thaw durability of plain concrete with water cement ratio of 0.60,0.55,0.50,0.45 and 0.40 was dealed with.The property degradation was described by relatve dynamic modulus and loss rate.The experiment results showed that with increasing the cycle time of freeze-thaw,the relative dynamic modulus varies linearly;the loss rate changes with different water cement ratio at the beginning,but the qualities of concrete with all the different water cement ratios decreased at the later stage. |
| |
| Keywords: | the cycle of freeze-thaw loss ratio relative dynamic modulus |
