摘要
根据混凝土冻融破坏的机理，并结合国内外的研究成果及三峡工程的施工经验．通过对混凝土抗冻性能的各种影响因素的综合分析，探讨了从混凝土原材料选择，优化配合比和加强混凝土生产、施工过程的控制来合理提高混凝土抗冻能力的途径。
Based on analysis on the mechanism of concrete failure resulting from the freezingand thawing, various factors effecting the resistance of concrete to freezing and thawing and combined with the research results at home and abroad and the experience in construction of the ThreeGorges Project, the means to rationally improve the resistance of concrete to freezing have been discussed on the grounds of the selection of concrete raw materials, optimization of mixes and controlof the concrete production and construction processes.[
