Superplasticising admixtures can be used to decrease the viscosity of concrete and decrease its water content. This improves the workability of the concrete or increases its strength when the water-cement ratio decreases. At the same time, the density and durability of the concrete improve. Superplasticisers can reduce the water demand by 5–30% without weakening the workability of the concrete.

Superplasticisers are surfactants, which attach themselves to the surface of the cement particles and cause repulsion forces to occur between them. Water is able to penetrate the spaces between the separated particles more easily and the workability of the concrete improves.


Finnsementti’s superplasticisers are CE marked.
