An increase in the strength of concrete is obtained by adding a superplasticizer and simultaneously lowering the water-cement ratio. The reduction of mixing water varies up to 30 %, depending on the dosage of the cement, water-cement ratio, type of cement and dosage of superplasticizers.

Workability, placeability and pumpability are improved by adding a superplasticizer without lowering the water-cement ratio. Cementol Zeta P - conc. is used for pre-cast concrete - enables higher initial strengths of concrete.
