Use of Water Reducers, Retarders, and Superplasticizer
Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used, that is from 5 to 20 liters per cubic meter of concrete.

Concrete superplasticizer is also known as a high range water reducer. It refers to an admixture that can reduce water consumption and increase the strength of concrete. It also refers to the admixture for saving cement in the condition of constant workability and strength.
Water Reducing Admixture for Concrete - Kingusn Chemicals
It is a concrete admixture that can reduce water consumption while the concrete slump is basically unchanged. As a concrete additive, water reducer for concrete plays a very important role in concrete applications. For example, the use of water-reducing admixtures can reduce the amount of water and increase the strength of concrete.
Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.

Poly Naphthalene Sulfonate (PNS) - Concrete Superplasticizer
Kingsun naphthalene sulfonate superplasticizer can significantly reduce the amount of water used and increase the strength of the concrete at each stage. When the concrete strength keeps constant, the cement can save 10% or more. Besides, it does not make the steel get rust because it has a small chloride ion content.
Superplasticizer - Wikipedia
Superplasticizers (SP's), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent.
