单面盐冻法评价路面混凝土抗冻性的适用性研究

Applicability of single surface salt frost to evaluate frost resistance of pavement concrete

在分析、比较国内外混凝土抗冻性试验方法的基础上,采用改进了的单面盐中冻融法测定不同强度等级、不同配合比的混凝土试件的抗冻性,认为该方法能有效地评价寒冷地区除冰盐环境中的混凝土的抗冻性能,并提出评价指标的建议参考值。

Based on the analysis and comparison of the domestic and international test methods about concrete frost resistance,this study adopted the improved method for single surface salt frost to measure frost resistance of concrete in different strength grade of concrete and in different water-cement ratio.This method can effectively evaluate frost resistance of concrete under deicing salt environment in cold region, and puts forward some suggestions of evaluation index system.
