In order to satisfy the characteristics of high speed,design service life long,project quality high demand of dedicated passenger line,this paper used fly ash and slag powder double mixed method,with the use of poly carboxylic acid water reducing agent,in the circumstances of reducing the total amount of cementitious material,prepared the high performance concrete with high intensity,high durability,high flow degree and high slump maintaining,provided basis for engineering application.%为满足客运专线运行速度高、设计使用年限久、工程质量要求高的特点,采用粉煤灰及磨细矿渣粉双掺的方法,配合使用高效聚羧酸减水剂,在降低胶凝材料总量的情况下,配置出具有高强、高耐久性、大流动度和高坍落度保持的高性能混凝土,为工程应用提供了基础。
