浅谈聚羧酸减水剂复配的应用

Application of Polycarboxylate Water Reducer Compound

对混凝土用聚羧酸减水剂工作性的影响因素及其规律入手,提出了改善聚羧酸减水剂工作性的可操作性措施,改变聚羧酸减水剂复配方案、增加各种辅助小料、优化其外加剂的掺量比例及消除引起不适应性的因素等,并列举了工程应用实例。

Starting with the influencing factors and laws of the workability of polycarboxylate superplasticizer for concrete,this paper puts forward some operable measures to improve the workability of polycarboxylate superplasticizer,such as changing the compounding scheme of polycarboxylate superplasticizer,adding various auxiliary small materials,optimizing the dosage ratio of its admixture and eliminating the factors causing inadaptability,etc.,and gives examples of engineering applications.
