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。 In this paper, the self-made polycarboxylate superplasticizer compound to examine the effect of the product after compounding on the performance of concrete, and through the study of different additives on the performance of the polycarboxylate superplasticizer, the cement The flowability of the paste, the initial slump and the strength of the concrete, the retarded effect of the retarder and the auxiliary plasticizing effect are obtained. The defoaming agent can obviously change the air content of the concrete and greatly increase the strength.
