Sikament® R4QV PK

High Range Water-Reducing and Slump Retaining Concrete Admixture

Sikament® R4QV PK is a highly effective dual action superplasticizer that imparts excellent slump retention for prolonged periods.
Suitable for use in hot and tropical climatic conditions.

Sikament® R4QV PK provides the following properties:
As a Superplasticizer
  • Workability is greatly improved
  • Concrete is placed easily
  • Especially suitable for slender components with densely packed reinforcement
  • Concrete requires less vibrating
  • Improved cohesion of the concrete mix significantly reduces the risk of segregation and allows greater time for placement
As a Water Reducer
  • Impressive water reduction capability; > 20% water reduction
  • Final strength improvement

Application Information

Compatibility

Sikament® R4QV PK may be combined with all types of Portland cement (OPC and SRC), concretes containing pozzolanic materials such as GGBS, PFA, micro-silica and the following Sika products:

  • SikaPump®
  • Sika® FerroGard®-901
  • SikaFume®-92 D PK
  • SikaFiber®
  • Sika® AER PK
  • Sika® Stabilizer
  • Sika®-1 WT
  • Sika® WT-10

We recommend performing trial mixes to establish the required performance when combining Sikament® R4QV PK with the above products or other admixtures. Please consult our Sika Technical Department.

Dispensing

Sikament® R4QV PK is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant. Do not add Sikament® R4QV PK directly to the dry mix. For optimum utilization of its high water reduction property we recommend thorough mixing at a minimal wet mixing time of 60 seconds.The addition of the remaining gauging water (to fine tune concrete consistency) may only be started after two-thirds of the wet mixing time to avoid surplus water in the concrete.
Consumption

Recommended Dosage

0.8 - 3 % by weight of binder. Higher dosages by weight of binder can be used depending on the mix design, raw materials, climatic conditions, and concrete requirements. 
Application steps

CLEANING OF TOOLS

Clean all tools & application equipment with water immediately after use.
