摘要
主要研究聚羧酸系高性能减水剂与几种常用外加剂的复配性能以及其在混凝土,特别是高强混凝土中的应用技术。结果表明:聚羧酸系高性能减水剂与氨基磺酸盐高效减水剂不能复配,与萘系高效减水剂的复配效果不甚理想,与木质素、葡萄糖酸钠可以按一定比例进行复配,与脂肪族高效减水剂复配比较理想;聚羧酸系高性能减水剂应用于高强混凝土有较大的优势,是配制C60及其以上高强混凝土不可或缺的优质减水剂。
It was mainly studied the compound behavior of poly-carboxylic series high-performance water-reducers with several common admixtures and their use technology of concrete,and especially high-strength concrete.The results show that it has a greater superiority for polycarboxylic series water-reducers to be used in high-strength concrete,which are the excellent water-reducer for preparing C60 and above C60 high-strength concretes.
