摘要
在国外,新一代超塑化剂已进入市场,聚羧酸盐类对水泥体系的作用机理区别于萘系等传统的超塑化剂。硅粉货源有限,可用高活性偏高岭土超细粉代替。俄罗斯研制成功的改性剂适于制造高强高性能混凝土。
New type of super-plasticizer has been put into market in foreign countries.The mechanism reacting with concrete of polymer carboxylic acid defers from traditional super-plasticizer such as naph-thalene.The supply source of silicon power is rare,but it may be re-placed with super-fine kaolin clay.The modifier developed by Russian is suitable for making high strength/high performance concrete.
