Classification: 22170500 [ACG587009]
| Preferred name | 22-17-05 混凝土添加剂 |
|---|---|
| Definition | 混凝土外加剂是一种溶于水或淤于水的添加剂，添加到混凝土中可以通过物理和/或化学作用改变新拌混凝土或硬质混凝土的性能，如加工性能、凝结性能、硬化性能或耐久性能。这些基金可以在混凝土工厂生产过程中直接添加，也可以在施工现场交付后添加。在施工现场添加的情况下，混凝土被称为添加外加剂之前的初始混凝土。由于混凝土外加剂的添加量很小，因此在配制混凝土配方时，与混凝土外加剂不同，混凝土外加剂不必作为体积成分考虑在内。这些外加剂包括混凝土冷凝剂、流动剂、稳定剂、引气剂、凝固促进剂、硬化促进剂、缓凝剂和密封剂。 |
