Sikament® F-4

High range water-reducing concrete admixture

Sikament® F-4 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® F-4 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
As high-range water reducer:
  • With up to 30% water reduction, and increase of the 28 days strength of up to 40% can be achieved
  • Early stength 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
As retempering of concrete:
  • Added into mixing truck on site to increase workability (slump) of concrete

Application

Application Information

Dispensing

Sikament® F-4 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® F-4 as manufactured by Sika. It shall be used in strict accordance to the manufacture's
recommendations.
Consumption

Recommended Dosage

Sikament® F-4 is dosed at normal rate of 0.6-2.5% by weight of cement.The exact dosage depends upon the effect required and should be established from laboratory trials.
Sikament® F-4 is compatible with all types of Portland Cement, including S.R.C. type and Hydraulic Cement.
