Uses and Benefits of Concrete Superplasticizer

Source: | Updated: Jan 18, 2016

Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a

mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture. Admixtures are used to modify

the properties of concrete or mortar to make them more suitable to work by hand or for other purposes such as saving mechanical energy. 


In precast production.

In plaster mortars where impermeability is desired to be improved.

In self compacting concrete.

In high performance concrete.

In architectural concrete.

In specially shaped concrete slabs.

In concrete production containing fly ash or silica fume.

In blast furnace slag concrete.

In lightweight concrete.

In marine concrete.

In pumping concrete.

For better filling of formworks designed with too many steel parts and having too much detail.

Features and Benefits

Gives the mortar excellent flow properties even if the water/cement (w/c) ratio is low.

Consumption is considerably smaller than that of conventional plasticizers.

Suitable for all cement systems in which the water requirement is to be reduced.

Produces extended slump life.

Improves the flow properties of the cement mix by dispersing the particles and preventing re-agglomeration.

Improves the rheological and mechanical properties of concrete such as workability, compressive and flexural strength, and modulus of elasticity.

Promotes usage of binders such as silica fume, fly ash and blast furnace slag.

Gives greater resistance to water permeability and freeze-thaw cycles.

Can be used together with other admixtures.

Improves finishing quality and workability.

Reduces cracking and permeability.

Does not contain chlorides or other ingredients promoting corrosion of steel reinforcement.
