1. When the strength and slump are basically the same,the amount of cement can be reduced by 10%-25%.
2. When the water-cement ratio is constant,the initial slump of concrete can be increased by more than 10cm,and the water reduction rate can reach 15%-25%.
3. It has significant early strength and enhancement effect on cockroaches,and its intensity increase range is 20%-60%.
4. It can improve the workability of concrete and improve the physical and mechanical properties of concrete.
5. It has good adaptability to various types of cement and good compatibility with other types of concrete admixtures.
6. Others:In the leather,textile and dye industries,it can also be used as a dispersant.
7. Especially suitable for:fluid concrete,plasticized concrete,steam curing concrete,impervious concrete,waterproof concrete,etc.
