Abstract Research purposes：Based on the analyses and comparison of the test items and quality control mode for the nuisance in concrete admixture at home and abroad，the suitable and effective way is offered for improving the control modes and the test items for the nuisance in the concrete admixture．
Research conclusions：The present single item control mode for the nuisance in concrete admixture，namely only control of the content of the nuisance in concrete admixture，can not meet the needs，SO it is suggested that the double items control modes，namely control of both the content of the nuisance in concrete admixture and the content of nuisance brought into soil，should be adopted for the nuisance in concrete admixture，which can satisfy the requirements of using the Polycarboxylate high performance water reducer and guaranteeing the concrete durability for construction of passenger dedicated line
