高速铁路无碴轨道用CA砂浆孔结构优化技术研究

Study of the pore structure optimum of the CA mortar of high speed railway ballastless track

将宏观性能测试试验和微观结构测试手段相结合,研究了沥青乳液、发气剂、减水剂及消泡剂对CA砂浆性能及微观孔结构的影响,探讨了各组分对CA砂浆性能的影响机理。同时对该复杂砂浆体系的微观孔结构形成机理进行了分析。

The effect of the asphalt emulsion,foaming agent,water-reducing agent and defoaming agent on the performance and pore structure of the CA mortar was studied by the combination of the performance testing and microstructure testing,the influence mechanism of the components on the CA mortar was investigated.The microstructure forming mechanism of the complex mortar system was also analyzed.
