摘　　要：聚羧酸减水剂减水效果好且使混凝土坍落度损失小，能够有效改善混凝土的工作性能。我公司从2008年10月份开始商品混凝土生产过程中全部使用聚羧酸减水剂。本文在我公司使用聚羧酸减水剂的实际具体情况的基础上，研究聚羧酸减水剂对高强度混凝土性能的影响，并与萘系减水剂进行对比，找出其优势与不足。Polycarboxylate based superplasticizer has better effect in reducing water and can keep lower concrete slump loss. It can improve the performance of concrete. Our company has been used polycarboxylate based superplasticizer in all commercial concrete production from October 2008. In this paper, based on actual situation of using polycarboxytate - type superplasticizer in our company, it studies the effect of polycarboxylate based superplasticizer on high - thalene superplasticizer, finds out the advantages and disadvantages strength commodity concrete, which compared with naph-thalene superplasticizer, finds out the advantages and disadvantages.
