客运专线高性能混凝土暂行技术条件

前 言

为统一铁路客运专线混凝土质量标准，明确混凝土施工控制技术要点，确保混凝土结构的长期耐久性能，制订本技术条件。

本技术条件主要依据京沪高速铁路高性能混凝土研究的最新成果、《铁路混凝土结构耐久性设计暂行规定》、《混凝土结构耐久性设计与施工指南》（CCES01-2004）以及国内外其它有关标准和规范编制。

本技术条件负责起草单位：铁道科学研究院、中铁十二局集团有限公司、中铁十七局集团有限公司 本技术条件主要起草人：谢永江 仲新华 黄直久 张 勇 郑新国 杨富民 朱长华 佟明华

李启棣 汪加蔚 刘世安 贾耀东

本技术条件由铁道部科学技术司负责解释。
