孔结构对混凝土抗冻性能影响规律研究进展

摘要

The research development of pore structures in frost resistance study of concrete was summarized.The common characteriza-tion parameters,the requirements of current codes,the evolution during freezing-thawing progress of pore structures were evaluated,and the problems of common testing methods were analyzed.On this basis,the further direction for the study of pore structures in frost resis-tance concrete was suggested.%对近年来混凝土抗冻性能研究工作中与孔结构相关的内容进行了总结，评述了孔结构常用表征参数、现行规范对孔结构的控制要求、冻融过程中孔结构演变过程研究，并分析了目前常用测试方法存在的问题。在此基础上对抗冻混凝土孔结构的研究提出了建议。
