混凝土外加剂与水泥之间的适应性问题长期以来影响着实际工程对外加剂的应用效果,使用的外加剂要进行适应性试验和掺量优选,使用过程中对外加剂质量和掺量要严格控制。所以为了改善和提高混凝土性能和施工性能,现在广泛采用化学外加剂作混凝土的第5组分来配制混凝上,在增加混凝土耐久性,提高工程质量,配制特种混凝土等方面,混凝土外加剂发挥了不可替代的作用。
The adaptability between concrete admixture and cement has long affected the application effect of actual engineering to admixture. The admixture to be used should be subjected to adaptability test and the dosage should be optimized. The quality and admixture should be strict control. Therefore, in order to improve and enhance the performance and construction performance of concrete, chemical admixtures are now widely used as the fifth component of concrete to be used in the preparation of concrete. In terms of increasing the durability of concrete, improving the quality of engineering and preparing special concrete, concrete admixtures are used Irreplaceable role.
