混凝土外加剂在工业发达的国家获得迅速发展与广泛应用,已成为混凝土中不可缺少的第五种成份。但在我国,外加剂使用还不广泛。其原因是应用技术的研究不够深入,产品没有系列化,复合型多用途的外加剂品种极少。我们必须进一步重视外加剂应用技术的研究;逐步实现产品系列化和生产厂布局合理化;提高产品质量;稳定价格等。为此,特提出建议如下: 一、充分认识应用外加剂的意义试验与生产实验都证明:在混凝土中恰当地应用外加剂,可节省水泥10～25%,可缩短蒸养周期1/3～1/2,节省能耗,提高产量;可提
Concrete admixtures have been rapidly developed and widely used in industrially developed countries and have become an indispensable fifth component in concrete. However, in China, the use of admixtures is not yet widely used. The reason for this is that the application technology has not been studied in depth, the products have not been serialized, and there are few varieties of composite multi-purpose admixtures. We must pay more attention to the research on the application technology of admixtures; gradually realize product serialization and rationalization of the layout of production plants; improve product quality; and stabilize prices. To this end, special recommendations are as follows: First, to fully understand the significance of the use of admixtures Experiments and production experiments have proved that: In the appropriate application of concrete additives, can save 10 to 25% of cement, can shorten the steaming cycle 1/3 ~ 1/2, save energy, increase production;
