铁路客运专线要求采用耐久性混凝土，其中对所用水泥的品质要求比常规混凝土严格，结合对《铁路混凝土结构耐久性设计暂行规定》和《铁路混凝土工程施工质量验收补充标准》的理解，介绍耐久性混凝土所需水泥的主要技术要求。

Longdurability concrete is required for the passengerdedicated railway works, which, compared to the ordinary concrete, imposes more strict requirements on the quality of the cements used. On basis of Chinese standards of "Temporary Stipulations on Design of Durability of Concrete Structures of Railway Works" and "Supplementary Standard on Acceptance of Construction Quality of Concrete Structures of Railway Works", the paper presents the major technical requirements on the cement quality imposed by the longdurability concrete.
