通过对比分别用萘系减水剂和Glenium〇R 6000 SDC系列聚羧酸减水剂配制的自密实混凝土的电通量和碳化深度，探讨两种减水剂对混凝土耐久性影响的差异。结果表明，采用Gle-nium〇R 6000SDC系列聚羧酸减水剂时，混凝土的抗氯离子渗透性和抗碳化性能比掺萘系减水剂时更优良；且当Glenium〇R 6000 SDC系列聚羧酸减水剂掺量增加，混凝土达到自密实状态时，早期强度虽略有降低，但抗碳化性能大幅提升。

The compressive strength , electric flux and carbonation depth of low binder self consolidation concrete with different superplasticizer types , Glenium〇R 6000SDC polycarboxylate superplasticizer dosage and water content were compared .In this way , all those factors on the durability of concrete were explored .The re-sults show that compared with concrete with naphthalene superplasticizer , concrete with Glenium〇R 6000 SDC polycarboxylate superplasticizer has higher compressive strength , better resistance to chloride ion and carbona-tion.With the increase of Glenium〇R 6000SDC polycarboxylate superplasticizer , concrete workability increased e-ven to self consolidation situation , early compressive strength decreased slightly , but carbonation resistance was improved dramatically .
