摘要
应用高分子设计原理,合成了一种低坍损聚羧酸系高效减水剂。考察了引发剂用量,单体配比及反应时间对其分散性能的影响,并用红外光谱表征了其结构。这类聚羧酸系高效减水剂可使新拌混凝土的坍落度一小时内几乎无损失。
Based on molecular design theory of polymer, a kind of low slump loss polycarboxylate type superplasticizer was synthesized. It studied the influence of the amount of initiator, the ratio of moners, reaction time on its performance, its structures were characterized by IR spectrum. The losses of slump was very small in 1 hour.
