| 摘 要： | 本文分别以气冻、干湿冻融、饱和冻融为条件,经过125次冻融循环,每25次冻融循环结束后对混凝土强度、质量进行对比,研究水工混凝土在冻融循环条件下的性能,得出在不同受冻条件下,混凝土经冻融循环后,在干湿冻融状态下的冻融破坏最为严重,其次是饱和冻融的结论。

| Abstract: | In the paper,air freezing,dry-humidity freeze thawing,and saturated freeze thawing are regarded as conditions respectively.Concrete strength and quality are compared after each 25 times freeze-thaw cycle after freeze-thaw cycle for 125 times.The performance of hydraulic concrete under the freeze-thaw cycle condition is studied.It is concluded that the concrete freeze-thaw damage is the most serious and saturated freez-thaw damage is the second most serious under dry-humidity freeze thawing state after freeze-thaw cycle under different freezing conditions. |
