摘要: 由于气候变化,现有气候分区内水工混凝土经历的冻融温度正在发生改变,采用研制的气候模拟系统,对不同强度等级、不同抗冻设计等级的水工混凝土在-30~-5℃冻融中心温度下进行了系统的冻融试验。研究提出了变化条件下水工混凝土冻融温度-强度等级-抗冻设计等级-冻融循环次数归因分析图。基于试验结果,对我国现行水工混凝土抗冻制度进行了探讨,分析了改变水工混凝土抗冻融中心温度对温室气体减排的影响。

Abstract: As a result of climate change, the freezing and thawing temperature of hydraulic concrete in different climate zoning is changing. The freezing and thawing tests of hydraulic concrete with different strength levels and different frost resistance levels were conducted under different low temperatures changed from -5℃ to -30℃ by using the self-made climate simulation system. An analysis chart about freezing and thawing temperature-strength grade-frost resistance design grade-maximum freezing and thawing cycles of hydraulic concrete was put forward according to the freezing and thawing tests result. The current anti-freeze system of hydraulic concrete was discussed in this paper. The indirect effects of low temperature of freezing and thawing test on greenhouse gas emission reductions were also analyzed.

Key words: freezing-thawing system, hydraulic concrete, durability, attribution analysis, conserve energy and emissions reduction
