The water reduction rate of high efficiency water reducer can reach more than 20%. Mainly naphthalene series, melamine series and water reducing agent compounded from them;
High-efficiency water-reducing agent has a strong dispersing effect on cement, which can greatly improve the fluidity of cement mixture and the slump of concrete, and at the same time greatly reduce the water consumption and significantly improve the workability of concrete. High-efficiency water-reducing agent basically does not change the setting time of concrete. When the amount is large (overdosed), it has a slight retarding effect, but it does not delay the growth of the early strength of hardened concrete.
Can greatly reduce water consumption and significantly increase the strength of concrete at all ages. When the strength is kept constant, cement can be saved by 10% or more.
