十三陵抽水蓄能电站上池防渗面板混凝土抗冻试验

Frost resistance test on seepage face slab in the upper reservoir of Shisanling Pumped storage Power Station

通过对十三陵抽水蓄能电站上池面板混凝土２６８ 组抗冻试验成果分析， 论证了混凝土抗冻试件的成型与养护方法对其性能有着不同程度的影响， “浸水”养护对试件的抗冻性能影响最大。为真实反映试件混凝土抗冻性能，建议在工程应用过程中， 试件采用“标养”或洒水、草袋覆盖养护方法。同时， 对规程的修订提出了意见和建议。

Based on the result analysis of frost tests on No.268 group of face slab concrete in the upper reservoir of Shisanling Pumped storage Power Station, this paper proves the shaping and curing methods of frost resistant specimen will bring different impacts on its properties. The 'soaking in water' curing method has the maximum impact on the frost resistant properties of specimen. In order to reflect really the frost resistant properties of specimen, it is suggested that in the practice of project, the specimen shall be cured by the methods of 'standard curing', spraying water curing, or using straw mattress to cover it. Meanwhile, this paper also puts forward some opinions and suggestions for the revision of 'specifications'.
