Sikament®-2000 AT

High range water reducing and set retarding concrete admixture

Sikament®-2000 AT is used as highly effective water-reducing agent and superplasticizer with set retarding effect for the production of high strength
concrete in hot climates.
Sikament®-2000 AT complies with ASTM C494 Type G.

Sikament®-2000 AT provides the following properties:
  • Substantial improvement in workability without increased water
  • Allow substantial cement reduction compared to plain concrete
  • Significant increase of ultimate strength
  • Especially suitable for concreting at elevated temperatures
  • Long lasting slump retention
  • Improved surface finish
  • Reduced shrinkage and creep
  • Chloride free

Usage

Sikament®-2000 AT is used especially for high strength concrete that needs long lasting slump retention under hot climate condition e.g:
  • Cast-on-site prestressed concrete
  • High strength bored piles
  • Bridges and cantilever structures
  • Slender components with densely packed reinforcement

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®-2000 AT can be added to the gauging water prior to its addition to the dry mix or separately to the freshly mixed concrete (on the batching plant or on job site into the truck mixer).
When added directly to the freshly mixed concrete, the plasticizing effect is more pronounced.
Consumption

Recommended Dosage

0.60–1.20 L per 100 kg of cement (Depend on cement type & brand)
Typical: 0.80–1.10 L per 100 kg of cement

Overdosing: Accidental overdosing of Sikament®-2000 AT causes an extension of the initial setting time.
