摘要
介绍聚羧酸系减水剂在满足铁路客运专线高性能混凝土综合性能方面的能力和特点,分析了工程应用中使用聚羧酸系减水剂存在的一些问题。提出解决聚羧酸系减水剂与水泥的相容性问题以及保持聚羧酸系减水剂本身质量稳定性是目前该减水剂应用的关键。
Polycarboxylates water-reducing admixture possesses the capability which could meat with the comprehensive performance of high performance concrete using in field of passenger dedicated line. Problems of engineering application of polycarboxylates water-reducing admixtures were analyzed. At present the key for polycarboxylates application is to settle the compatibility with cement and keep the quality retention of this admixtures.
