Sika® Super-1

HIGH RANGE WATER-REDUCING CONCRETE ADMIXTURE

Sika® Super-1 is a high-range water reducer type concrete admixture of the new generation for the production of high strength concrete with increased acceleration for early strength development.

Sika® Super-1 provides the following properties:
As superplasticizer:
  • Substantial improvement in workability without increase of w/c ratio
  • No segregation
  • Normal set without retardation
  • Accelerated hardening after setting
  • Improved density and surface finish (no honeycomb)
As high-range water reducer:
  • Greater than 20% water reduction, and increase of the 28 days strength of up to 40% can be achieved
  • Early strength increased of more than 100% can easily be achieved (depending on dosage and w/c ratio)
  • Increased impermeability to water
  • Improved resistance to wear and abrasion

Application

Application Information

Dispensing

Sika® Super-1 can be added separately to the freshly mixed concrete, or directly to the gauging water prior its addition to the dry mix. When added separately to the mix, a further mixing of at least one minute should take place. It is typical that a later addition of superplasticizer to the concrete would improve the workability retention.

Restrictions

Concrete shall contain the superplasticizer which shall be Sika® Super-1 as manufactured by Sika. It shall be used in strict accordance to the manufacture's recommendations.
Consumption

Recommended Dosage

0.5 litre per one bag of cement (50 kilograms weight).
Sika® Super-1 is compatible with all types of Portland Cement, including S.R.C. type and Hydraulic Cement.
