Sika® ViscoCrete®-3614 SKY

(former MasterGlenium® Sky 3614)

High Range Workability - Retaining Admixture

Sika® ViscoCrete®-3614 SKY admixture is a revolutionary new technology superplasticiser, based on significant advances in admixture chemistry. Sika® ViscoCrete®-3614 SKY admixture is used as part of an admixture system to provide customized admixture solutions for a wide range of concrete applications. Sika® ViscoCrete®-3614 SKY admixture is a workability-retaining admixture that provides extended, flexible degrees of slump retention without retardation. Sika® ViscoCrete®-3614 SKY admixture provides the concrete producer with the ability to immediately create the optimal admixture system for changing and fluctuating regional raw materials, environmental conditions, and project requirements. Sika® ViscoCrete®-3614 SKY admixture gives the concrete producer the ability to consistently produce and deliver quality concrete mixtures. Sika® ViscoCrete®-3614 SKY admixture offers extended workability retention for high range concrete mix designs for long distance travel or extended workability requirement applications.

  • Workability retention without retardation.
  • Flexible levels of workability retention by adjusting the dosage.
  • Improved early and late-age compressive strengths.
     
Sika® ViscoCrete®-3614 SKY offers the following benefits:
  • Promotes greater consistency of concrete workability at the job site.
  • Promotes consistency in compressive strengths via minimized job site addition of water.
  • Minimizes re-dosing of high-range water-reducing ad-mixture at the job site.
  • Fewer rejected loads and better customer satisfaction due to consistent quality of concrete.
  • Faster truck turn-around time.
  • Expanded concrete delivery range.

Product Information

Shelf Life

Sika® ViscoCrete®-3614 SKY admixture has a minimum shelf life of 12 months from date of manufacture.

Depending on storage conditions, the shelf life may be greater than stated.

Storage Conditions

Sika® ViscoCrete®-3614 SKY admixture must be stored at temperatures above 5°C. If Sika® ViscoCrete®-3614 SKY admixture freezes, thaw and reconstitute by mechanical agitation. Do not use pressurized air for agitation.

Sika® ViscoCrete®-3614 SKY admixture is not UV stable and may experience different colour shades between different batches and/or may darken over time. This does not affect product performance in any way.

System information

Compatibility

Sika® ViscoCrete®-3614 SKY admixture is compatible with most admixtures used in the production of quality concrete, including normal, mid-range and high-range water reducing admixtures, air-entrainers, accelerators, retarders, extended set control admixtures, corrosion inhibitors, and shrinkage reducers.

     

Sika® ViscoCrete®-3614 SKY admixture has only been tested with admixtures manufactured by Sika South Africa (Pty) Ltd. As a result, use of Sika® ViscoCrete®-3614 SKY admixture with non-Sika South Africa (Pty) Ltd admixtures may produce unpredictable results.

         
Non-Chloride, Non-Corrosive: Sika® ViscoCrete®-3614 SKY admixture will neither initiate nor promote corrosion of reinforcing steel embedded in concrete, prestressing steel or of galvanized steel floor and roof systems. Neither calcium chloride nor other chloride-based ingredients are used in the manufacture of Sika® ViscoCrete®-3614 SKY.

     

Do not use Sika® ViscoCrete®-3614 SKY admixture with admixtures containing beta-naphthalene sulfonate. Erratic behaviours in slump, workability retention and pumpability may be experienced.

   

Application

Application Information

Dispensing

Sika® ViscoCrete®-3614 SKY admixture can be added with the initial batch water or as a delayed addition.

Other dosages may be recommended in special cases or applications according to the specific site conditions or material requirements. In this case, please consult our Technical Services Department for advice.
Consumption

Recommended Dosage

Sika® ViscoCrete®-3614 SKY admixture has a recommended dosage range of 600 - 1800 mL/100 kg of cementitious materials.

   

Sika® ViscoCrete®-3614 SKY admixture offers extended workability concrete. Targeted workability retention needs to be measured through preliminary testing and final site evaluation with relevant concrete materials and site conditions to established fixed retention periods in relation to dosage.
