Sikament® F-2

High Range Water-Reducing Concrete Admixture

Sikament® F2 is a high-range water reducer (HRWR) type concrete admixture of the new generation for the production of high strength concrete with increased acceleration for early strength development.

Sikament® F2 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

Usage

Sikament® F2 is used as superplasticizer for flowing concrete at:
  • Slabs and Foundations

Application

Application Information

Compatibility

Sikament® F-2 is compatible with all types of Portland Cement, including S.R.C. type and Hydraulic Cement.

Dispensing

Sikament® F2 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 be designed in accordance with ACI 211.1-89 standard
recommended practise for selecting proportions for concrete and shall
contain the superplasticizer which shall be Sikament® F2 as manufactured by Sika. It shall be used in strict accordance to the manufacture's
recommendations.
Consumption

Recommended Dosage

Sikament® F-2 is dosed at normal rate of 600 - 2,500 CC. per 100 kg. of cement weight.The exact dosage depends upon the effect required and
should be established from laboratory trials.
