摘　　要：分别选用3种无机早强组分(NS、CS、CN)和2种有机早强组分(DMEA、TEA)与聚羧酸减水剂(CGM)进行二元、三元复配,对复配前后的新拌混凝土流动度和硬化混凝土各龄期强度进行测试,提出了不同类型的早强组分与聚羧酸减水剂复配试验的早强规律。结果表明,无机-有机-CGM三元复配比无机-CGM、有机-CGM二元复配体系具有更好的的早期增强效果。Inorganic （NS, CS, GN） and organic （DMEA,TEA） accelerants were introduced to combine with polycarboxylate super- plasticizer （CGM） in binary and ternary forms. The fluidity of fresh concrete and compressive strength of concrete at different ages were investigated with and without these accelerants,which was used to evaluate the early strength rules. The result indicated that the inorganic-organic-CGM ternary compound system had better combination effect than inorganic-CGM or organic-CGM forms.
