Sika® ViscoCrete®-10

HWRRe High Range Water Reducer Retarder

Sika® ViscoCrete®-10 is a third generation superplasticiser for concrete and mortar. It meets the requirements for set retarding / high range water reducing superplasticisers according to AS1478.1-2000.

Sika® ViscoCrete®-10 is a powerful superplasticiser which acts through several different mechanisms including surface adsorption and sterical effects separating the cementitious binder particles. The following advantageous properties are achieved:
  • High water reduction, resulting in high density, high strength and reduced permeability
  • Superior plasticising effect, resulting in improved flow, placing and compaction characteristics
  • Reduced shrinkage during curing and reduced creep when hardened
Sika® ViscoCrete®-10 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.

Usage

Sika® ViscoCrete®-10 is especially suitable for concrete mixes with extended transportation times and extended workability requirements, high water reduction and improved flow characteristics. Sika® ViscoCrete®-10 is mainly used for the following applications:
  • Concrete with ultra high water reduction (up to 30%)
  • High performance concrete
  • Concrete in hot weather and with extended transportation and workability requirements

Modified polycarboxylate in water.

Shelf Life

12 months from date of production if stored properly in undamaged unopened, original sealed packaging.

Storage Conditions

In dry conditions at temperatures between +5°C and +30°C. Protect from direct sunlight and frost.

It requires recirculation when held in storage for extended periods.
Technical Information

Concreting Guidance

The standard rules of good concreting practice, concerning production and placing, are to be followed.

Laboratory trials shall be carried out before concreting on site, especially when using a new mix design or producing new concrete components.

Fresh concrete must be cured properly and curing applied as early as possible.

Application

Application Information

Compatibility

Sika® ViscoCrete® can be used in conjunction with all the admixtures manufactured by Sika NZ Limited.

All admixtures must be added separately.

For additional information, please contact Sika technical personnel.

DISPENSING

Sika® ViscoCrete®-10 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, which is depending on the mixing conditions and mixer performance, of at least 60 seconds per cubic metre after the admixture addition is recommended.

To avoid excess water in the concrete, the final dosage must begin only after 2/3 of the wet mixing time.
Consumption

Recommended Dosage

Recommended dosage for concrete:
250 ml to 2000 ml per 100 kg of total cementitious material.

Optimum dosage should be determined by site trials.
