摘　　要：板式无砟轨道的优越性已经被世界许多建设高速铁路的国家和地区认可。我国高速铁路的建设大多也采用此项技术,在引进国外先进技术的基础上,通过硅酸盐水泥与磨细矿粉的复合使用来代替国外超细水泥,生产出工作性能、力学性能和耐久性能符合要求的CRTS Ⅱ型无砟轨道混凝土轨道板,创造了良好的经济效益和社会效益。The advantages of ballastless track slab had been approved by many countries and regions that construct high-speed railway in the world.High-speed railway in china mostly also constructed by the technology, in introducing foreign advanced technology foundation, Portland cement and ground fine slag powder was used to instead of the foreign superfine cement, producing work performance, mechanical properties and durability concrete to meet the requirements of CRTS Ⅱ ballasfless track slab, and create a good economic and social benefits.
