聚羧酸减水剂与缓凝组分相容性的探究

Research about component compatibility of polycarboxylate superplasticizers and retarding

研究了葡萄糖酸钠、焦亚磷酸钠、六偏磷酸钠、硼砂等各种缓凝剂分别与聚羧酸减水剂共同使用对水泥净浆流动性及水泥初凝时间和终凝时间的影响。结果表明:葡萄糖酸钠、六偏磷酸钠等无机、有机缓凝剂与减水剂复合使用后能提高混凝土工作性能。

Study of sodium gluconate,coke sodium phosphite,six partial sodium phosphate,borax etc of retarder with poly carboxylic acid water reducing agent in common use on the fluidity of cement paste and concrete time of initial setting and final setting time effect.The results show that：the sodium gluconate,six partial sodium phosphate and other inorganic,organic inhibitor and superplasticizers after use can improve the working performance of concrete.
