各种助剂与聚羧酸减水剂的复配研究

Compound research of polycarboxylic acid and various other aids

本文通过对自制的聚羧酸减水剂进行复配,考察复配后的产品对混凝土的工作性能的影响,并通过研究不同的添加剂对复配后的聚羧酸减水剂的性能、水泥净浆流动性、初始坍落度及混凝土强度的影响,得出缓凝剂明显的缓凝作用和辅助塑化效应,消泡剂可以明显改变混凝土的含气量,强度也大幅提高。

This paper studied the effect of the compounded acid with self-made polycarboxylic acid and various other aids on the workable,strength and initial slump of the concrete,fluidity of cement mortar.The results showed that,concrete can be significant retarded and auxiliary plasticized with the additives of retarding agent.Defoaming agent can change air content of concrete and improved concrete strength greatly.
