浅析水工建筑物混凝土的冻融破坏

Analysis of the Destruction by the Freeze and Thaw for Hydraulic Structure Concrete

根据混凝土冻融破坏的机理,并结合国内外的研究成果及经验,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及质量控制,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。

This paper approaches concrete raw material selection and quality control, optimizing coordination ratio, strengthen concrete production ,control production processing to reasonably improve concrete ability against freeze, by way of synthesis analysis the various factors impacted concrete performance according to the mechanism destroyed of freeze and thaw.
