摘要
通过自由基接枝聚合反应合成得到聚羧酸,一般依据所使用到大单体的种类,将其划分为酯类和醚类。本文主要研究了不同组成和不同掺量下两类聚羧酸在自密实混凝土中的应用。实验结果表明,在给定配合比和原材料的前提下,自密实混凝土良好的工作性,可以通过简单的调整聚羧酸的种类和掺量来实现。
Polycarboxylate superplasticizers are synthesized by radical graft copolymerization reaction,and the products are divided into ester series and ether series on the basis of different big monomers.This article studies on influence of the different composition and dosages of the synthetic superplasticizers in the self-compacting concrete(SCC).The results show that the requirements of SCC workability can be achieved through simple adjustment kinds and dosages of the synthetic superplasticizers under the given mix proportions and the raw materials.
