预应力无砟轨道板用封锚砂浆

Preparation of sealed mortar used in prestressed track board without ballast

结合相关标准要求以及工程实际情况,选择合适的原材料通过合理的配合比设计,配制符合工程要求的预应力轨道板用封锚砂浆,并相应的研究了封锚砂浆的搅拌、成型工艺。

According to the requirement of practical engineering, the preparation and design of the sealed mortar that used in prestressed track board were investigated.Besides, the rational mixing and molding process of such mortar were also studied.
