摘 要: | 通过试验分析了冻融循环对混凝土抗压、抗折、劈拉强度的影响,并从微观结构探讨了混凝土冻融破坏机理。结果表明普通低标号混凝土抗冻性能较差,冻融循环对混凝土强度影响较大。

The influence of freeze-thaw to concrete strength |
| |
Abstract: | Based on test,the article has analyzed the influence of freeze-thaw cycles to concrete compressive strength, flexural strength and cleavage strength, then approached mechanism of fracture by freeze-thaw on micro-structure. The result indicated that the resistance to freezing and thawing of normal low-strength concrete is very low. Freeze-thaw cycles have important affect to concrete strength. |

Keywords: | concrete strength freezing and thawing durability |
