摘要
本文研制了一种适用于CRTSⅢ型板式无砟轨道板的微膨胀自密实混凝土,它具有工作性好、填充无缺陷、开裂敏感性低和耐久性好等优点,性能满足TJ/GW 112—2013《高速铁路CRTSⅢ型板式无砟轨道自密实混凝土暂行技术条件》要求。
This paper introduces a micro-expansion self-compacting concrete which is suitable for CTRSIII ballastless track. This concrete has the advantage of good workability, without filling defect, low cracking sensitivity, and good durability. In addition, its performance can satisfy the requirements of TJ/GW 112-2013.
