- 抗冻混凝土比普通混凝土的耐久性要求高。文章在介绍有关标准对抗冻混凝土技术要求的基础上,根据试验结论和实践经验,总结出提高混凝土抗冻性能的有效途径。
For freezing resistant concrete higher durability is required than that for common concrete.After introducing relevant standards on technical requirements for freezing resistant concrete, this article, based on test results and practical experiences, summarizes the eff6cient ways to raise the freezing resistance ability, that is, adding air-intiating agent, strictly controlling water-cement ra-tio, selecting proper cement kinds, proper cement quality, main material with good freezing resist-ance ability, optimum sand ratio and proper construction season.1991,6(6): 9-12 收稿日期：1991-3-5参考文献：
