Use of Water Reducers, Retarders, and Superplasticizers.

It is necessary to ensure that the superplasticizers do not become fixed with C 3 A in cement particle, which will cause reduction in concrete workability. 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.
