Sika® ViscoCrete®-1050 HE

HIGH PERFORMANCE SUPERPLASTICISER

Sika® ViscoCrete®-1050 HE is a third generation superplasticiser for concrete and mortar. It is designed particularly for production of precast concrete that demands high early strength and high ultimate strength.

Sika® ViscoCrete®-1050 HE is a powerful superplasticiser based on advanced technology which gives the following advantages :
  • High water reduction, resulting in high density, high strength and reduced permeability.
  • Extended workability in conjunction with subsequent fast strength development.
  • Excellent plasticising effect, resulting in improved flow, placing and compaction characteristics.
  • Reduced shrinkage during curing and reduced creep when hardened.
  • Provides many opportunities for cost improvement e.g.: Cement reduction, More economic mix design, Reduced energy costs for steam cured precast elements, Reduction of potential claims etc.
Sika® ViscoCrete®-1050 HE does not contain chlorides or any other ingredients which promote the corrosion of steel. It is therefore suitable for use in reinforced and prestressed concrete structures.

Overview

Usage

Sika® ViscoCrete®-1050 HE is a unique multi purpose superplasticiser that is particularly suitable for the production of precast concrete. Additionally it provides ultra high water reduction, high early strength and excellent flow characteristics.
With its outstanding combination of good workability and early strength development Sika® ViscoCrete®-1050 HE is used for the following :
  • A wide range of applications where good early strength development are required.
  • Concrete with ultra high water reduction (up to 30%).
  • High performance concretes
  • Self Compacting Concrete (SCC)

Concreting guidance

The standard rules of good concreting practice, concerning production and placing, are to be followed.
Laboratory trials before concreting on site are strongly recommended when using a new mix design or producing new concrete components.
Fresh concrete must be cured properly and as early as possible.

Application

Compatibility

Sika® ViscoCrete®-1050 HE may be combined with the following products:

    Plastiment® P121R
    Plastiment® VZ
    Sika® Fume
    SikaFibre®

Do not use viscocrete / viscoflow series combined with sikament series.

To produce flowing and / or self-compacting concrete, special concrete mix design is required.

Pre-trials are recommended and mandatory if combinations with the above products are required.

Please consult to our Technical Service Department.

DISPENSING

Sika® ViscoCrete®-1050 HE is added to the gauging water or added with it into the concrete mixer.
To take advantage of the high water reduction, a wet mixing time of at least 60 seconds is recommended.

Recommended dosage

For medium workability:

0.2 - 0.8 % by weight of cement

For concrete with high workability, very low water/cement ratio and for Self Compacting Concrete:1.0 - 2.0 % by weight of cement
