摘要
介绍了聚氧乙烯基烯丙酯大单体和聚羧酸减水剂的合成,并对合成的聚羧酸减水剂进行了性能考察。考察结果表明,所合成的JH23聚羧酸减水剂符合缓凝高效减水剂的性能要求,且主要性能指标优于GB 8076-1997《混凝土外加剂》标准要求。
Acrylate monomer with polyoxyethylene group chain and a series of polycarboxylic superplasticizer were synthesized and their water-reducing effects were investigated. Testing results showed that JH23 polycarboxylic superplasticizers synthesized met the requirements to retarding-type high range water reducing agent. Their main performance indexes were superior to those set in GB 8076-1997 《Concrete Additives》Standard.
