摘要
介绍了JY-PCA型聚羧酸系高性能减水剂的合成,重点研究了该减水剂的性能。研究表明,JY-PCA型聚羧酸系高性能减水剂具有良好的减水效果与保坍性能,与传统萘系减水剂相比,聚羧酸系高性能减水剂可以明显改善混凝土的收缩性能。
The paper introduces the composition of JY-PCA polycarboxylic high performance water-reducing agent,mainly researches the performance of the water-reducing agent,shows that the composition of JY-PCA polycarboxylic high performance water-reducing agent has better water-reducing effect and slump loss-preventing agent,and the polycarboxylic high performance water-reducing agent can improve the shrinking property of the concrete compared with traditional naphthalene water-reducing agent.
