负温C50高性能混凝土受冻临界强度研究

摘要

结合哈尔滨西站轨道层C50高性能混凝土的施工，从施工试验、数据分析、临界强度确定等几方面对高性能负温混凝土受冻临界强度进行了研究。%In this paper, in combination with the concrete construction of the Harbin West Station track layer C50 high- performance, from construction testing, data analysis, and other aspects, critical strength of high-performance negative temperature eoncrete is studied.
