乌鲁木齐市城市轨道交通近期建设规划(2012~2019年),城市轨道交通共规划有7条线路。高性能混凝土(HPC)以耐久性作为设计的主要指标,针对不同用途要求,对耐久性、工作性、适用性、强度、体积稳定性和经济性等性能重点予以保证,其配制上的特点是采用低水胶比,选用优质原材料,掺加足够数量的掺合料(矿物细掺料)和外加剂等保证混凝土性能。本文针对C30混凝土,从原材料选取,针对环境作用等级进行配合比设计,耐久性试验等多方面进行混凝土试验研究重点,设计出满足轨道交通设计年限及要求的高性能混凝土。
Urumqi, the recent urban rail transit construction planning (2012 ~ 2019), urban rail transit total planning of seven lines. High performance concrete (HPC) durability as a major indicator of the design, according to the requirements of different uses, durability, workability, applicability, strength, volume stability and economy and other performance focus to be guaranteed, the preparation is characterized by The use of low water-cement ratio, the selection of high-quality raw materials, mixed with a sufficient amount of admixture (mineral fine admixtures) and additives to ensure concrete performance. In this paper, C30 concrete, from the selection of raw materials, according to the level of environmental effects of mix design, durability test and so on many aspects of concrete test research, design to meet the rail transit design life and requirements of high performance concrete.
