摘   要：北方地区机场道面对混凝土材料的耐盐冻性能有较高要求，引气混凝土的使用能有效增强其盐冻耐久性。本文测试了两种典型引气混凝土在不同掺量下的盐冻剥蚀量，基于混凝土孔结构分析方法，利用“CAD简化法”和Matlab编程，统计计算出试件的孔径分布、平均孔径和孔间系数等参数并分别研究各参数对混凝土盐冻耐久性的影响。从微观层面评价了引气剂对机场道面混凝土盐冻耐久性的改善作用，为寒冷地区机场道面材料的研究与应用提供参考。

Abstract: Airfield runway in the north area has higher requirements for the frost resistance durability of the concrete material and the use of air-entrained concrete can effectively enhance its frost resistance durability. The scaled mass of two typical kinds of air-entrained concrete under different parameters is tested in this paper. Based on the analysis of the pore structure, “CAD simplified method” and the Matlab programming, the parameters of stomatal distribution, average pore diameter and inter-hole coefficient for the specimen are statistically calculated and the relationship between them and frost resistance durability of concrete are studied. The improvements of concrete frost resistance durability are evaluated by the air entraining agent, which can offer references to the research and application of airfield runway material in the cold area.
