SikaPlast® R4QV CD PK

Concrete Admixture For High Flow / Self-Compacting Concrete

SikaPlast® R4QV CD PK is a third-generation super- plasticizer for concrete and mortar. It is particularly developed to produce high flow concrete with exceptional flow retention properties. This product is suitable for use in hot climatic conditions.

  SikaPlast® R4QV CD PK acts by surface absorption on the cement particles producing a sterical sep- aration effect on the cement particles. Concrete produced with SikaPlast® R4QV CD PK exhibits the following properties:
▪Excellent flowability (resulting in highly reduced placing and compacting efforts)
▪Strong self-compacting behaviour
▪Extremely high water reduction; > 25% (resulting in high density and strengths)
▪Increased high early strength development
▪Improved shrinkage and creep behaviour
▪Reduced rate of carbonation of the concrete SikaPlast® R4QV CD PK does not contain chlorides or other steel corrosion promoting ingredients. Therefore, it maybe used without restriction for reinforced and prestressed concrete construction. SikaPlast® R4QV CD PK gives the concrete ex- tended workability and depending on the mix design and the quality of material used, self-com pacting properties can be maintained for more than 1 hour at 30°C.

Usage

SikaPlast® R4QV CD PK facilities extreme water re- duction, excellent flowability with optimal cohesion and strong self-compacting behavior. SikaPlast® R4QV CD PK is used for the following types of concrete:
▪High flow concrete
▪Self-compacting, concrete (S.C.C.)
▪Concrete with high water reduction (upto 30%)
▪High strength concrete
The combination of high-water reduction, excellent flowability and high early strength provides clear benefits in the above-mentioned applica- tions.

Application

Application Information

Compatibility

SikaPlast® R4QV CD PK may be combined with many other Sika products particularly:
▪Sika pump
▪Sika Fume
▪Sika Retarder and Sika Retardol-25
Pre-trails must be performed before combining products in a con- crete mix. Please consult our technical services department for fur- ther advice and information.

Dispensing

SikaPlast® R4QV CD PK is added to the gauging water or simultan- eously poured with it into the concrete mixer. For optimum utiliza- tion 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

▪For soft plastic concrete 0.3 - 1% by weight of blinder
▪For flowing and self-compacting concrete 0.6 - 1.5% by weight of binder.
▪Higher dosage upto 2% by weight of binder can be used depending
in the mix design & concrete requirement.
A pre-trial using local material sources to confirm the dosage must be done by the user.
*Note: Set retardation may occur at dosage greater than 1.0% with some binders.
Application steps

CLEANING OF TOOLS

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