What is superplasticizer for concrete?

Superplasticizer to an additive that can greatly reduce the amount of mixing water under the condition that the slump of the concrete is kept basically the same.Superplasticizer 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.

However, some superplasticizer will accelerate the slump loss of concrete. Superplasticizer basically does not change the setting time of concrete. When the amount is large (overdose added), it has a slight retarding effect, but it does not delay the early strength growth 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.

The chloride ion content is minimal, and it does not cause corrosion to the steel bars.

It can enhance the impermeability, freeze-thaw resistance and corrosion resistance of concrete, and improve the durability of concrete.
