A highly effective superplasticizer with a set retarding effect for producing free-flowing concrete in hot climate and also a substantial water reducing agent for promoting ultimate strength.

USES

Sikament V4 superplasticizer is used for flowable concrete in:

- Floor slabs

- Foundations

- Slender components with densely packed reinforcement

- Walls

- Columns

- Beams

Sikament V4 provides the following properties:

As a superplasticizer:

- Highly effective without increased w/c ratio or the risk of segregation

- Lasting control of slump loss

- No adverse effect on ultimate strength

As a water reducer:

- Ultimate strength significantly increased

-Allow substantial cement reduction compared to plain concrete

- Especially suitable for hot climate

- No excessive air entrainment

- No adverse shrinkage effect

- Improved surface finish

- Increased watertightness

Dosage: 0.60 - 1.10 ltr per 100 kg of cement

Typical Dosage: 0.70 - 1.00 ltr per 100 kg of cement

Compatibility: Possible to combine with all Sikament, Sika Aer, Sika Pump, Sikacrete PP1, but must be added separately to the mix and not pre-mixed prior addition.

Cement types: All Portland cement including sulfate resistant cement.

Dispensing: Sikament V4 can be added directly to the gauging water prior to its addi-tion to the dry mixed aggregates or simultaneously with the gauging water at the batching plant. When added directly to the freshly mixed concrete, the plasticizing effect is more pronounced. For addition at job site, Sikament V4 is added to the concrete immediately prior to discharge and after further mixing has taken place for three min-utes.

Overdosing Significant overdosage will result in increased workability and setting time of the concrete. However, provided concrete is cured effectively, ultimate strength and properties will not be affected.
