Self-compacting concrete is the key technology of CRTS Ⅲ plate type ballastless track. The CRTS Ⅲ plate type ballastless track filling layer pouring construction puts forward almost stringent requirements to self-compacting concrete pouring construction. Combined with the CRTS Ⅲ plate type ballastless track filling layer pouring construction requirements of Zhengzhou- Xuzhou Passenger Dedicated Line, this paper analyzes the impact of polycarboxylate superplasticizer on the properties of self-compacting concrete, and determines the impact law of polycarboxylate superplasticizer on the properties of self-compacting concrete.
