无砟轨道构件预制要求必须保证混凝土在带模养护的条件下获得较高的早期强度,选用粉煤灰、矿粉双掺和早强高效减水剂,优化板式无砟轨道钢筋混凝土配合比设计,实现了每天一个循环的生产目标,并且创造了良好的社会和经济效益。
Prefabricated requirements of ballastless track members must ensure that the concrete in the mold curing conditions to obtain a higher early strength, the choice of fly ash, mineral double-doped and early strength of superplasticizer, optimization of slab-track reinforced concrete mix design , Achieved a cycle of production goals a day, and created good social and economic benefits.
