High-efficiency water reducing agent has a strong dispersing effect on cement, which can greatly improve the fluidity of cement mixture and concrete slump. At the same time, it greatly reduces water consumption and significantly improves the workability of concrete. However, some high-efficiency water-reducing agents will accelerate the slump loss of concrete. When the dosage is large (excessive dosage), they have a slight retarding effect, but they do not delay the growth of the early strength of hardened concrete.
It can significantly reduce water consumption and thus significantly increase the strength of concrete at all ages. When maintaining a constant strength value, cement can be saved by 10% or more.
The content of hydrogen ions is very small and does not cause corrosion to steel bars. It can enhance the impermeability, frost resistance and corrosion resistance of concrete, and improve the durability of concrete.
