Sikament®-294

High range water-reducing and set retarding concrete admixture

A highly effective superplasticizer with a set retarding effect for producing flowable concrete in hot climate and also a substantial water reducing agent for promoting ultimate strength.
Sikament®-294 complies with ASTM C494 Type D & G.

Sikament®-294 provides the following properties:
As a superplasticizer with set retarding effect:
  • Highly effective without increased w/c ratio
  • Lasting control of slump loss
  • Controlled setting time
  • Avoidance of cold joints
  • No adverse effect on ultimate strength
As a water reducer:
  • 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

Usage

Sikament®-294 is used as a superplasticizer and set-retarding admixture in structural and mass concrete where long lasting slump and a controlled extension of setting time is required, such as:
  • Large volume pours
  • Long hauls concrete
  • Foundations
  • Floor slabs
  • Slender components with densely packed reinforcement
  • Walls, columns, beams

Application

Application Information

Compatibility

Possible to combine with all Sikament®, Sika® Aer, Sika® Pump, Sikacrete® PP-1, but must be added separately to the mix and not pre-mixed prior addition.

DISPENSING

Sikament®-294 can be added directly to the gauging water prior to its addition 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®-294 is added to the concrete immediately prior to discharge and after further mixing has taken place for three minutes.
Consumption

Recommended Dosage

0.60–2.00 L per 100 kg of cement
Typical:

0.80–1.60 L per 100 kg of cement
1.40–2.00 for special bore pile application

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.
Note: Due to extended setting time, proper curing must be ensured.
Do not vibrate green concrete or temper embedded rebars whilst setting.
