摘要
通过对比分别用萘系减水剂和Glenium6000SDC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Glenium6000SDC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Glenium6000SDC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 .
