Abstract：In order to configure high performanceconcrete forconstruction，this paper takes the type and dosage of water reducing agent as variables，and determines the optimal type and dosage of water reducing agent through slump test，impermeability test and compression test.The results show that under the same dosage，the working performanceofconcrete mixed with polycarboxylate superplasticizeris beter than thatof concrete with naiseries superplasticizer.With the increaseof the proportionof waterreducing agent，the slumpofconcrete increases，the electric fluxdecreases，the compressive strength increases，and even the strength grade of concretecan be improved. Therefore，it is suggested to add 0.3% polycarboxylic acid water reducing agent or 0.4% nai water reducing agent. Key words： concrete ; working performance;dosage;mix ratio;water reducing agent
